About me
I’m a Computer Engineer and Senior Flutter Developer with 7+ years on Fiverr, Top Rated status, and 250+ five-star reviews. I build production-ready Android and iOS apps for startups and businesses across the US, Europe, and Australia.
I specialise in complete Flutter MVPs using Firebase or Supabase, AI-powered features with OpenAI or Gemini, RevenueCat subscriptions, and fixing existing apps. I also handle crashes, performance issues, iOS deployment, FlutterFlow, and AI-generated codebases.
Send me your idea or broken build, and I’ll reply with a clear plan.
