Shipyard: Creator Contest is a mobile app-building challenge where real influencers enlist you to build, launch, and monetize an MVP mobile app for their audience. In four weeks or less.
Earlier this year, we began evaluating Compose Multiplatform (CMP) in our production apps. Not as a replacement, but as a way to meaningfully reduce duplication and bring our teams closer together. This post is a reflection on that journey: what worked, what didn’t, and the lessons we’ve learned so far.
Imagine writing your business logic once and watching it run flawlessly on both Android and iOS. No duplicate codebases. No synchronization nightmares. No “but it works on Android” excuses.

Technical deep dives, or solving the "how-the-hell-do-I-test-this" problems.
Practical Kotlin Deep Dive takes you beneath the surface of Kotlin, exploring not just what the language does, but how it works and why it was built that way. From foundational concepts through coroutines, compiler architecture, and Kotlin Multiplatform, this book connects everyday coding patterns to their underlying mechanisms.
Compose Hot Reload has just been promoted to stable with our 1.0.0 release. We worked hard to build a technology that is easy to use and well-integrated into existing tools while also requiring zero configuration from users.
Handling permissions in Kotlin Multiplatform (KMP) is one of those areas where naive abstractions break very quickly because Android and iOS have fundamentally different permission models.
How a single feature becomes a cross-platform, architecturally clean, fully testable slice of a real KMP system.
This is the second part of an educational series about dependency injection. In the first article, we implemented dependency injection manually. In this one, we take the exact same example and let Koin do the wiring for us.
Ktorfit brings the familiar Retrofit-style annotations and structure into the multiplatform realm, built on top of Ktor and powered by Kotlin Symbol Processing (KSP).
