Zimvo Matwa.

Mobile developer building cross-platform apps that don't feel like they were built cross-platform. Advanced Flutter and modern Android — MVVM, Clean Architecture, Jetpack — with a bias toward scalable systems, tight APIs, and code that ages well.

(01) about

I design and ship mobile products end-to-end — features from concept to release, with real test coverage, profiling passes, and CI that catches the boring stuff before humans do.

I work best in small, high-trust teams. Two-person squads, direct lines to design and product, and a bias toward shipping something small every week instead of a rewrite every quarter.
