01 About //

Android developer with nine years of shipping native apps that people open every day. I build in Kotlin and Jetpack Compose, care deeply about smooth 60 fps scrolling, small APKs and cold starts under a second, and I like architecture that a new teammate can understand on their first afternoon.

I've taken products from blank Gradle project to millions of installs, migrated legacy Java codebases to Compose without a feature freeze, and built offline-first sync engines that survive tunnels, elevators and airplane mode. Off the clock I mentor juniors, write about Android performance and occasionally contribute to open-source libraries.

> Based in Inowroclaw, Poland · Remote-friendly across EU & US time zones.
