Welcome & Hello! 🫂​

For some of you, this has been the loveliest month of the year, has it not? 😜 Do not worry if you do not belong to this category of humans for we neither judge nor discriminate. 🤗 As Android254/Kotlin Kenya, we love to love our community members and this past meetup was nothing short of proof of our commitment to providing value to them. We know that some of you missed that amazing event and that is why you are reading this, whether it is from the comfort of your German Machine 🚗 or otherwise...

This is Episode #24 of The Kotlin Kenya Monthly Newsletter... ✍️

Bug Squashers, Feature Code: How Streeek Engineers Build, Ship, and Repeat 🔁​

If you are passionate about washing dishes 🧽 and stuff, then this was the session for you. Jokes aside, The Chief Senior Dishwasher, GDE took the attendees through an engaging 'Show and Tell' kind of session featuring his team's latest product, Streeek. By the end of this session or rather masterclass or maybe crash course, the audience acquired the skills needed to successfully build, ship, and iterate on an Android product straight from Ideation 🧠 to Production ✅...

Mastering Efficient Data Loading with Android Paging 🌀​

Are you a fanatic of Performance in Android? 😃 If so, then you should have definitely attended the session held by Benard Mathu. He rigorously demonstrated how to use the Paging library to efficiently load data. This session enhanced the Performance skills of the attendees as they later received some goodies 🎁 for participating in the Q and A segment ✋, just like with the other sessions. Do you now see why you should not have missed out on this?

Hai 🤑​

To close the day, Sam Ngigi wasted no time ⏳ in showcasing his latest product, Hai, since time is money 💰. Hai is an Android app that is primarily tailored to solve your Financial Health issues by allowing you to:

• Automatically backup/sync all our SMS M-pesa transaction records to your google sheets...
• Get Yearly and Monthly Summary/Retrospectives on spending and income with relevant insights...

Do we even need to tell you how awed the audience was when they were educated on the value that this product would provide to their Financial Health? 😮 Stay tuned for more updates on Hai...

The Announcement 📣​

We have an announcement. This is a big one. It is probably our biggest one yet so you better not skip this part 🤨. As you know, Android254/Kotlin Kenya is the best Tech community to ever exist, right? 😌 I mean, can you deny that? 😏 Anyway, to coincide with that fact, we are proud to announce that we will soon be launching an Android app for the community 🥳. Yes, yes, and yes. Soon, you will no longer have to switch between different platforms to access everything about us. From the sessions, to the announcements, to even the newsletter, you will be able to access all of these and much more from the comfort of your smartphone 📱. Of course, we know that you guys [and gals] love building so we will provide you with the GitHub Repository for the app so that you can join us in crafting a product that is built by the community for the community. Does this sound good? 😉 All that we ask is that you follow us on our socials to be in the loop once we make the announcement. We cannot wait to collaborate with you on that project so stay tuned... 👂

Seamless Camera and Media Access on Android 14+ and Legacy Versions 📷​

If you have been following Android's evolution [as you should 🤨], then you know that Permissions are central to each iteration of the popular OS. With the introduction of Runtime Permission Handling in Marshmallow ⬜️, Android has been rapidly adjusting how these Permisisons are provided. To agree with this, Valentine Rutto wrote this article 🗒️ that talks about Seamless Camera and Media Access on Android 14+ and Legacy Versions. In her words, "Android 13+ and later versions introduced significant changes in how apps access media files. The adoption of granular permissions requires app updates to ensure proper functionality. This post provides a code overview for capturing an image, saving it to storage, and retrieving it on devices running Android 13+, 14+ as well as older versions."...

Welcome & Hello! 🫂​

Can you hear that? 👂 The sound of a new beginning? We hope you can for we certainly are glad to be back. Happy New Year 2025, Android Engineers. 👋 How are you? Are you ready to kickstart yet another year filled with nothing but the code? Worry not, for this newsletter summarises all that the first meetup of this year sought to promise the attendees. Spoiler alert: They were promised the good stuff...

This is Episode #23 of The Kotlin Kenya Monthly Newsletter... ✍️

The Panel Discussion 👥​

Moderated by Emmanuel Muturia™, we had a Panel Discussion talking about Job Hunting and Open Source in 2025. We are fully aware of the difficulties of Job Hunting this season and because of that, we sought to discuss the strategies that our attendees could take advantage of to get hired and drive those German Machines to our future meetups. 🚗 Jokes aside, we were joined by Ben Salcie and Kenneth Murerwa who shared their insights on topics such as Upskilling, Interview Preparation, and even Career Progression as a Junior Android Engineer...

The Feedback Session 💬​

We value our community members. 😉 We value them so much, that we held the usual Feedback Session where they got to tell us what worked and did not work last year and most importantly, what they wanted to see this year.

Do you have any feedback, suggestions, complaints, or anything nice to tell us? Waste no time and click me... 👍

HarmonyOS 📱​

If you thought that Android and iOS were the only operating systems for Mobile, then how wrong you are. 😱 You would be forgiven, though, for we were introduced to HarmonyOS, an operating system made in China not just for Mobile but for pretty much any device. All the way from Europe, Jasper Morgan, the CEO of Snapp Mobile, gave a thorough talk on HarmonyOS and how to build apps for it. 💻 It is safe to say that despite the meetup being Kotlin-first the attendees were at the very least curious about this new innovation and wondered how they could get involved... 🤔

Feature of The Month 🙌​

Would it not be great if coding was more...fun? 🤔 Well, more like a game than actual work? 😮‍💨 Sounds cool, right? Do you know what is cooler than that? The game actually exists. 😲 Let us explain:

"Over the holiday season, I had the privilege of leading a team of two amazing android engineers to turn a fun idea into reality: a GitHub-based game that makes contributing to open source both competitive and rewarding. After countless hours of brainstorming, coding, and testing, we shipped the MVP for Streeek!

🎯 Key Highlights:

• In just one day, the app garnered 30 downloads, thanks to sharing it with friends and colleagues who were equally excited about the concept.
• By establishing a clear development and release process, we were able to iterate faster, resolve blockers efficiently, and launch the MVP within a tight timeline.

🌟 Streeek is all about gamifying GitHub contributions to keep developers motivated while having fun. Check it out and join the streak:

🔗 GitHub: https://lnkd.in/dr8sy7Q2

📱 Play Store: https://lnkd.in/dqtRyU76

💡 More insights on the development process, team collaboration, and lessons learned will be coming soon in a series of articles.

Stay tuned!" ~ The Chief Senior Dishwasher, GDE

Welcome & Hello! 🫂​

When the cat is away, the mice will play. Similarly, when the sun is out, the developers will shine as we near the end of the year. You would think that we were slowing down but you would probably be forgiven as we are switching gears (Tech Bros, please relax). We know that you are curious to know what has been happening this month and that is where we come in as Problem-Solvng is our middle name. This is Episode #22 of The Kotlin Kenya Newsletter:

Overcoming The MockK Struggle 🧪​

The first session vibrantly kicked off with Rachel Murabula using the analogy of car parts to introduce MockK as a Testing Library. She took the audience through the steps needed to write tests using MockK by use of a whiteboard in a way that would make you think that it was a classic DSA Session...

Principles for Effective Session Delivery 📣​

Without wasting any time, Mambo Bryan engaged the audience and rightfully so because he educated the members on how to deliver world-class sessions. Using the example of everybody's favourite topic (Kotlin Coroutines), he gave a step-by-step demonstration of how to conduct sessions like an expert (If you know you know). In addition, a lengthy discussion was made and the following were the key takeaways that we hope you will go and research on:

• Kotlin Flows and Suspending Functions (Find out how their implementations in Room were changed in Room 3.x)...
• Concurrency and Parallelism...

DroidCon Kenya 2024 🎟️​

Have you still not bought your tickets to the most exciting annual event in the history of Android in Kenya? 🤦‍♂️ If we said that we had more goodies (and that is a big "If") for the first few buyers then would that motivate you to head over to droidcon.co.ke and get your tickets? There you go then, you sneaky developers. 😏 Head over to droidcon.co.ke and grab your tickets as you never know what awaits you from the 6th to the 8th of November this year... 🙃

Feature of The Month 🙌​

Many developers know how to survive screen rotations using ViewModel or rememberSaveable, but the bigger questions remain: Why does state get lost in the first place? Why is ViewModel often the go-to solution, and is it the only one? What about other scenarios, like process death or user-initiated closures?

Unlike desktop or web environments, Android apps run on a wide range of devices with different hardware capabilities, varying screen sizes, and limited resources like memory and battery. Moreover, the Android operating system is designed to be highly dynamic, frequently creating and destroying activities and fragments to optimize resource usage and preserve battery life. This means that your app's state can be lost or reset at almost any time if not managed properly.

In this first release of Android Hot and Ready, Preserving Your Android App State, we share insights and practical strategies for managing state in your Android apps. From handling configuration changes to preparing for process death, we've covered a range of solutions to keep your app’s state alive and ensure a great user experience.

Before You Go... 🏃‍♂️​

Do you want to have your product (app, article, video, etc) featured in the next episode? Worry not for all you need to do is reach out to us at either Android254 or Kotlin Kenya and include the details of your product. What are you waiting for? Let us get to work, shall we?

Until October 🫂​

It is at this point that we acknowledge our new beginnings and pledge 🤚 to have a transformative 2024. We have journeyed, are journeying, and will still journey with you. Gears are about to be shifted (Tech Bros please calm down) in your favour. If you would like to level up your career in Android, then attending the monthly meetups, building cool stuff in public, and interacting with community members should be a part of your routine. We cannot wait to hear and share your stories. See you in October! 👋

Welcome & Hello! 🫂​

Whoa whoa relax guys. We know that you dearly missed us and we missed you too. Winter Season may have separated us but we are here yet again to occupy your professional lives and help you achieve your goals. Do we even need to tell you how this month is different from the rest? Did you not see our poster? Well, join us in this episode as we uncover what Android254 and Kotlin Kenya have been up to this month. This is Episode #21 of The Kotlin Kenya Newsletter!

The Kotlin Bits Challenge 🧠​

To supercharge our attendees' problem-solving skills, we had them attempt an easy LeetCode problem. If you are up for it, feel free to submit your solution to us and who knows, you just might win a prize...

Asynchronous Programming with Coroutines 🌀​

Joining us from the city of Abuja, Michael Obi took the stage (well, screen as it was virtual but you get the idea) and made the audience understand why Asynchronous Programming was important in the first place. Using screenshots from a language that we shall not name, he demonstrated different use cases for Threads within the context (pun intended) of expensive tasks...

The Open Bar Session 💬​

To conclude the meetup, we had an Open Bar session that was kickstarted by Emmanuel Muturia™ who showed off ArtMaker to the audience and encouraged them to check it out and learn more about the Canvas API in Jetpack Compose. Next, Samuel Juma demonstrated SuperStocks which is a compose multiplatform project that gets Realtime data for the top 10 companies around the world, by market capitalization and was designed to work on Kotlin Multiplatform (KMP), and is of course the new kid in the block of Android App Development (AAD). This was followed by Oscar Karuga who made a comeback by introducing the community members to FeynmanAI which is a powerful command-line tool that leverages the Retrieval-Augmented Generation (RAG) model to interact with local documents. Whether you want to query your documents for specific information or quiz yourself on the contents, FeynmanAi offers an intuitive interface to get answers and enhance your understanding.. Lastly, the attendees were educated on Paystack as a FinTech product and did you know that they were recently acquired by Stripe?

The Newset GDE in Town 🕺​

If you have been around for a while, then you will understand that certain things were just a matter of time. What we are about to announce is certainly at the top of the list. Without wasting any time, join us in congratulating The Chief Senior Dishwasher in being officially recognised by Google as a Google Developer Expert (GDE) for Android! Thus, to mark the initiation complete, we officially declare him as The Chief Senior Dishwasher, GDE...

Are you interested in learning more about the Canvas API and Custom Drawing in Jetpack Compose? Would you like to unlock the Picasso (not the library) in you programmatically? Look no further as we would like to present to you ArtMaker by Ferdinand Bada, Caleb Langat, and Emmanuel Muturia™. ArtMaker is a flexible and customisable library that allows users to draw anything they want on screen and has been built fully with Jetpack Compose. It allows drawing through the Canvas, sharing the drawn Bitmap, or programmatically exposing the Bitmap for use in the calling application...

Welcomes & Hellos! 🫂​

Winter Season is here, fellow Android Developers! As you keep on building while sipping your favourite hot beverage, we would like to entertain you with the usual monthly compensation. While we genuinely wish it came with a dollar sign and lots of zeros at the end, we believe that ours will most certainly get you there. This is Episode #20 of The Kotlin Kenya Newsletter!

The Virtual Opening Session​

This meetup was not your ordinary one and in case you did not catch it, this is KotlinConf' Nairobi! Can you believe that? Kotlin's biggest event was held not just in Coppenhagen but in Nairobi too. Well, the extended version at least but it is something, nonetheless. As you know and are probably sick of hearing by now, we take great pride in the speakers that grace our stages and the one who opened the ceremony was no exception as she is, well, exceptional. Pamela Hill was kind enough to mark the event open and offer various insights on KotlinConf' 2024...

The KotlinConfGlobal: Nairobi Challenge​

Do you remember what we said about a challenge where the top 3 contestants would receive goodies? Guess what? It happened and do we even need to tell you how excited The Chief Senior Dishwasher was when he concluded The KotlinConfGlobal: Nairobi Challenge and awarded the winners?

The Amper Moment (Goodbye, Gradle?)​

As if we did not have any more value to offer, we had The Chief Senior Dishwasher who wasted no efforts in ranting, sorry we mean educating the audience on Amper, which we honestly know as The Gradle Destroyer. He took the attendees through how Amper aims to improve the developer experience for Android and KMP development. Are you as patient (impatient, rather) as we are for its official release?

Until July 🫂​

It is at this point that we acknowledge our new beginnings and pledge 🤚 to have a transformative 2024. We have journeyed, are journeying, and will still journey with you.

The April Challenge 🧠​

DSA Gurus, please calm down. After a lengthy waiting period (how inefficient of us 😮‍💨) since our previous announcement, The Chief Senior Dishwasher has put up The April Challenge. Do we even need to tell you to head over there to solve it at this point? Go on, now. Flex those algorithmic muscles 💪 and show off your LeetCode skills to your fellow programmers while hoping to somehow apply them in your Take Home Assignments... 🤡

Designing Scalable Compose APIs 👨‍💻​

Bonjour! If you thought that we had the last encounter of Yves Kalume, GDE 🇨🇩, then nous sommes désolés for we pride ourselves in our international reach. ✈️ Armed with his expertise and experience working with Jetpack Compose, Yves walked the audience through Designing Scalable Compose APIS by explaining the Dos and Don'ts of the same. From Detecting Quality APIS to Component Layering to Component Nomenclature, The GDE (Android) ensured that the attendees walked out of the room fully armed with the knowledge they needed to design and scale their Compose APIs...

What's New in Android, Development Tools, and Google Play 📱​

You might want to get a king-sized bucket of popcorn 🍿 for this section as it was a show to remember. Being an Android Engineer comes with its fair share of pain 🥲 often prescribed and administered by Google. As if to console the internal tears of afflicted developers and his fellow Arsenal supporters, Mr. Arsenal played therapist and conducted a session to discuss the challenges faced by Android Engineers when deploying their apps to the Google Play Store. Various individuals shared their areas of concern while some confessed that they had their accounts banned and were left with no choice but to do nothing but hope for a miracle. Mr. Arsenal gave his takes on the issues discussed and even offered helpful tips and tricks for handling the strict guidelines issued by Google. Arsenal finally did deliver something, did they not? 🤧

Welcomes & Hellos! 🫂​

Hello and hello again, everyone 👋! How are you all? We hope that you are safe and sound despite the reenactment of The Noah Floods 🌊. We are not referring to this Noah but you get the idea 🤷‍♂️. Without wasting any time, here is a recap of what happened this month within the Android254 and Kotlin Kenya communities. This is Episode #18 of The Kotlin Kenya Newsletter:

The April Challenge​

Do you love a good Linked List Manipulation Session? Are you a DSA guru who drools over reversing, recursing, and linking Linked Lists? 🥵 Whether you are or not, The Chief Senior Dishwasher unveiled The April Challenge. It featured Recursion 🌀 as the concept of choice to make the Test Cases pass. Let us do this one more time: Would you like to win some merch by JetBrains? If so, then be ready to fire up The Kotlin Playground and solve The April Challenge when it drops at KotlinBits.

Exploring Canvas in Jetpack Compose for Better UI Experiences 🎨​

The Hutsy Developer made good use of an ice breaker (if you know you know) ⛏️ to introduce his session on working with Canvas in Jetpack Compose. Like the Tech Bro that he is, Josphat Mwania used the Audi logo to demonstrate how to work with Canvas in Jetpack Compose using the Canvas API. Josphat concluded his session by challenging the audience to apply what they learnt to draw either the Instagram logo or the Facebook logo. The Senior Teaman took up the challenge and submitted this solution.

Exploring Mobile Release Management: Strategies & Best Practices 📊​

If you hate complex release processes when it comes to Mobile Releases, then you no doubt need to check out The State Machinist's presentation on the different strategies and best practices of Mobile Release Management. He extensively talked about Release Management, The Challenges of Mobile Release Management, and The Solutions too. To learn more, check out his presentation. 📈

Configuring WorkManager: Running Tasks in The Background 🔧​

Finally, we were served (pun intended but keep reading even if you do not understand) with a taste of Background Process Scheduling using WorkManager by Joel Muraguri. He used a simple Reminder app to demonstrate the steps needed to implement WorkManager in Android to schedule 🗓️ background tasks.

Food for Thought 💡​

• Do you think WorkManager will work when a user toggles "Background Processes" off on his/her app settings? ⚙️ Why?

• If you schedule a task, say 10 minutes ⏲️ from now, do you think it will be executed if the app is not in the foreground when the time comes for the task to be executed? Why?

Welcomes & Hellos!​

If laughter is the best medicine then we are no doubt the best doctors 💉 in Kenya for our attendees had quite some laughs during The March Meetup courtesy of our lively speakers. Even if you did not get the chance to attend The March Meetup, worry not for this release will simulate them as we believe in leaving no man (or woman) behind. This is Newsletter #17:

Keeping Your Software Fresh: How Renovate Simplifies Dependency Updates​

Have you ever struggled to keep your dependencies up to date in this dynamic field of Android? Or even worse, have you ever had to deal with Ancient Dependencies? You would be forgiven after thinking that Dependabots were the only solution to this unfortunate circumstance. What if we told you that there was another way? 😮 What if we told you that it prioritises Automation? Yes, people of DevOps. This new option targets you too. Without wasting any time, Brandy Odhiambo introduced Renovate as an automated solution that seeks to ease the process of Dependency Management. In fact, we dare to say that Renovate might be better for you compared to Dependabots thanks to:

• The Dependency Dashboard that provides all of the information you need regarding your dependencies...
• The ability to upgrade common monorepo packages...
• The Multi-Platform support...
• The ability to show log changes...
• The ability to run as often as it is allowed to run...

Say goodbye to Ancient Code (Interns and Juniors we are watching you) and say hello to Automation...

State Management in Jetpack Compose​

Speaking of Ancient Code, are you still stuck writing your UI in XML and would like to migrate to Jetpack Compose? Would you like to take a step further and learn about State Management in Jetpack Compose? We had The Beerman take us through State Management where he implemented The Beer App 🍺 to demonstrate the same.

Here are a few pointers that were discussed during this session:

• State and State Management...
• State Hoisting...
• Definition of State in Kotlin (Jetpack Compose)...

Stay tuned for a potential Part 2 of this elaborate session 😉...

Get Started with Gemini on Android​

From ChatGPT to Dall-E and now Devin, AI seems to be moving faster than most of us thought. Whether that is a good or bad thing, we cannot deny that AI is here to stay and we are all better off understanding it even at a basic level.

Given that we do not want our developers to be rendered obsolete, we invited The Droidette to conduct a workshop on Getting Started with Gemini on Android. She made use of Chat Buddy to demonstrate the power of Machine Learning through Artificial Intelligence using The Gemini API in Android. The audience was in awe for this marked a revolution of sorts in the potential of AI in building attractive ❇️, user-friendly 🤗, robust 🦾, and testable 🧪 Android apps...

The March Challenge​

Are you a lover of Data Structures and Algorithms? Do you not just love a good LeetCode session where Performance 📈 is your love language? Worry no more for whether you like it or not, we decided to feature Linked Lists in The March Challenge anyway 🤷‍♂️:

Oh no. We did not just stop there. Android254 and Kotlin Kenya firmly believes in Test Driven Development (TDD). "Yes that is great and all, but how does that relate with the March Challenge?" That is the best question you could have asked for all you need to do is click me and test your Testing skills. See what we did there? 😏

DroidCon Kenya 2024​

The early bird 🐦 catches the worm 🪱. While we will not be catching worms any time soon, we are proud to announce that DroidCon Kenya 2024 will be happening from the 6th to the 8th of November this year.

The Teaman made this announcement and gave the following pointers that we would like you to have:

Welcome!​

Hi, Droids and Droidettes! Welcome back to yet another issue of The Kotlin Kenya Newsletter 📃. How have you all been? We hope that you had an awesome February and that you experienced the love that you deserved this month 😏. Whether you did or not, let us demonstrate our love for you by releasing this month's issue of our Newsletter. This is Newsletter #16:

The Kotlin Monthly Challenge​

During this month's meetup, our audience got to stretch their thinking by participating in The Challenge #2 as well as flexing their Kotlin and DSA prowess. This epsisode focused on both Kotlin-specific and Algortithmic approaches to solving The Challenge and by attempting it yourself, you could see how well your code would have performed at the time. Share with us your solutions as what better way to market your skills than through flexing them at any given point in time? 🤷‍♂️

The Code Review​

Do you still feel like you could write better code? Does your GitHub repository still look like that of a Bedroom Developer? Worry not for we have permanently adopted The Code Review as part of our Monthly Meetup Curriculum. For the second time, we were joined by The Teaman who went over the following pointers (pun intended if you know C++) based on this GitHub repository:

1. Commenting vs Documentation​

Senior Chepsi mentioned that while opinions may differ regarding its implementation and execution, documentation is important in a team-centered codebase. He stressed that documentation allows for readability of the codebase regardless of the seniority of the reader.

2. Write Out Why You Chose It​

In addtion, he emphasised that another feature of a well-documented codebase or GitHub repository was the inclusion of the "why", that is, documenting why you chose a certain library for example. The attendees were made to understand that why they chose their tools mattered more than what tools they actually used.

3. Network Calls​

Through a lengthy but fruitful discussion, Chepsi engaged the crowd by asking them which technologies they used for making network calls in their projects. The most outstanding takeaway was that majority of the community members preferred Ktor as it supported their mission of adopting a Kotlin-first approach to building their projects.

The session and meetup in general was concluded by the attendees being asked to try and play around with their technologies and even try and build their own. A custom network-calling tool, perhaps? Food for thought.

The Call For Speakers (Monthly Meetup)​

Hi (The Reunion)​

Hi Droids and Droidettes and a Happy New Year to you 🤯. How have you all been? Now that you are back so are we! Without wasting any time, here is what's been happening in Android254 and Kotlin Kenya. This is Newsletter #15:

The Kotlin Challenge​

Hey psst! Are you a Kotlin junkie who would like to flex their Kotlin muscles? You are? In that case, please thank your colleagues led by The Chief Senior Dishwasher who brought back The Kotlin Challenge. The Kotlin Challenge is an opportunity for you to not only showcase your Kotlin prowess, but also claim your very own Jetbrains Lincense. What else, apart from a German Machine could be more rewarding for your skills? 😏

The Expectations, Feedback, and Topics​

With a new year comes a new way of doing things. As we are a community and not a regime, we always seek to involve our community members in our development plans (pun intended 🤡). During the January Meetup, we had a lengthy yet engaging discussion based on the following pillars:

1. Expectations​

With the steady incorporation of new members, Android254 and Kotlin Kenya received the latter's expectations for their experience in the community. They were as interesting as the proposition to include pizza snacks 🍕 and as resourceful as including more hands-on workshops. Tell a friend to bring a friend in order to find out more, will ya?

2. Feedback​

We also gathered valuable feedback from our community members and do you guys have quite the ideas! In case you participated in our survey, then please be assured that we have already assimilated your feedback into our plans for the year. The question is: Are you ready for what's coming? 👀

3. Topics​

Finally, we got the best responses from our attendees concerning the topics that are in high demand. In case you wanted to see more of Kotlin MultiPlatform (KMP), Career Stuff, Android Automotive, etc then just attend our next meetups. That's it, really 🤷‍♂️...

The Code Review​

Are you a novice who would want to be put to the flame of Code Reviewing? Would you like to have a Senior Engineer (or even a GDE 😜) assess the quality of your work? we are pleased to announce that we are now having Code Reviews as part of our community activities. January's meetup saw The Teaman conduct a Code Review Session using this GitHub repository. The audience learnt best practices, mistakes to avoid, as well as hacks pertaining take-home assignments...

The KotlinConf' 2024 Contest​

If you thought that we are your average Tech community then you are as lost as J*va enthusiasts 🚮. In preparation for KotlinConf' 2024, we are proud to announce that we have Samson Aricha as one of the winners for The KotlinConf' Contest 🥳. Check out his product and learn from the best...

Whoa whoa whoa there! Did you seriously think that we had only one winner? Once again KotlinConf' announced Asira Etemesi as another champion for The KotlinConf' 2024 Contest. Head over to his product to learn more...
