About this Gig

I am a professional Flutter & Android Developer with strong experience in Java, Kotlin, and Dart, specializing in mobile app bug fixing, maintenance, optimization, and feature development. I work with both existing apps and new projects, helping clients fix issues, improve performance, and build reliable mobile applications.

If your app is crashing, freezing, slow, unfinished, or poorly coded, I can analyze the problem and fix it correctly. I also help recover abandoned or half-built apps, refactor messy code, and make apps stable, scalable, and production-ready.
