About me
I’m a software developer based in Warsaw, Poland, with a degree from the Warsaw University of Technology (Faculty of Electronics and Information Technology).
I’ve been building mobile applications professionally since 2010 — starting with iOS, and expanding into cross-platform mobile over the past eight years. First via Java with j2objc, now with Kotlin Multiplatform (KMP), sharing business logic between iOS and Android. Swift is still my home, but the shared layer is where a lot of the interesting architecture decisions happen.
