Informazioni su questo servizio

I will build, fix, or debug your FlutterFlow app to ensure it works correctly, reliably, and is ready for real users.


Whether you are starting a new FlutterFlow project, fixing broken logic, or struggling with bugs, I help you structure, debug, and stabilize your app properly no hacks, no trial and error.

I focus on clean logic, correct data flow, and long-term maintainability, not quick workarounds.

What I can help you with:

  • FlutterFlow app build or completion
  • Fixing broken UI, logic, or workflows
  • Debugging actions, conditions, and state issues
  • Firebase / backend connection issues
  • Authentication and user flow problems
  • API integrations in FlutterFlow
  • App crashes or unexpected behavior
  • Preparing your FlutterFlow app for release

This gig is ideal for:

  • FlutterFlow MVPs that dont work as expected
  • Apps stuck due to logic or backend issues
  • Founders who want a working app, not experiments
  • Projects taken over from another developer

Important notes:

  • This gig is for FlutterFlow only
  • New features shall be discussed upfront
  • Access to your FlutterFlow project is required
  • Complexity depends on your current setup


Please contact me before ordering and briefly explain your Issues
