About this gig

Are you stuck with a Flutter bug that's holding up your app? Whether it's a broken layout, a state management nightmare, or a failed API call I can help you track it down and fix it fast.


What I fix:

-UI and layout issues (overflow, alignment, responsive problems)

-State management bugs (Provider, Riverpod, GetX, BLoC)

-API and HTTP errors (REST, JSON parsing, null safety)

-App crashes, runtime exceptions, and Dart errors

-Widget rendering and navigation issues


Why choose me:

-I work cleanly and communicate clearly at every step. You'll get fixed code plus a brief note -explaining what was wrong so you understand the solution not just a patch.


To get started, please share:

-Your Flutter project files or the relevant code

-A clear description of the bug and expected behavior

-Any error messages or screenshots


Let's get your app back on track!
