About this gig

Is your Flutter app broken, slow, or difficult to maintain?


I can help you fix bugs, improve performance, clean up your code, and make your app more reliable.


Im a mobile app developer with 10+ years of experience building real apps, MVPs, games, internal tools, and business systems. I work with Flutter, Dart, Firebase, Supabase, APIs, and clean app architecture.


I can help with:

  • Flutter bug fixing
  • App crashes and errors
  • UI issues
  • Firebase or Supabase problems
  • API integration issues
  • Performance improvements
  • Code cleanup
  • State management issues
  • Android and iOS app problems


My focus is not just writing code. I try to understand what the app should do, what is broken, and how to fix it properly.

Before starting, I will review the issue and tell you honestly what can be done.


Message me before ordering so I can check the problem and suggest the best package.
