At PT Universe Solusi Digital, I develop Flutter applications with maintainable architecture, turn designs into responsive interfaces, and integrate REST APIs. I also support CI/CD and distribute builds through Firebase App Distribution.

Previously, I developed marketplace and toll-road monitoring apps, as well as event, logistics, education, and inventory apps. I’ve worked on map-based experiences, operational workflows, automated testing, crash monitoring, and app releases using Flutter and Dart.
