Is your FlutterFlow app stuck with bugs, Firebase auth errors, broken APIs, custom widget issues, or failed deployment?


I help founders and app owners diagnose, fix, and stabilize FlutterFlow projects without unnecessary rebuilding. Whether your app has login problems, broken navigation, REST API failures, Firebase connection errors, custom action bugs, UI issues, or release problems, I focus on finding the real cause and getting the affected flow working properly.


What I can help with:

  • FlutterFlow bug fixing and debugging
  • Firebase authentication and database errors
  • REST API and third-party integration issues
  • Custom widgets, actions, and app logic
  • Android and iOS build or deployment problems
  • Performance checks and stability improvements


You get clear communication, careful testing, source code access where required, and a clean handoff after the fix. I work within the agreed scope and keep you updated so you always know what is being repaired.


Send me the issue, screenshots, error message, or project details before ordering, and Ill recommend the right package for your FlutterFlow app.
