About this gig

Got a Flutter app, Codecanyon template, AI generated app, or vibe coded MVP that is buggy, incomplete, slow, or hard to maintain? I can help you fix, reskin, revamp, optimize, and make it stable for real users.


I specialize in Flutter app bug fixing, Flutter app reskin, Firebase issues, API integration, app crashes, UI fixes, performance optimization, app cleanup, and production-ready improvements for Android and iOS apps.


I can help with:

  • Flutter bug fixes and crash issues
  • Codecanyon Flutter app customization
  • AI generated or vibe coded app cleanup
  • Firebase, database, auth, and notification fixes
  • REST API integration and backend connection issues
  • UI revamp, app reskin, splash screen, and icon updates
  • App performance, stability, and compatibility improvements
  • Play Store / App Store build and release support


My experience includes Flutter, Firebase, NestJS APIs, chat apps, social apps, dating apps, finance apps, and production mobile apps.


Please contact me before ordering so I can review your app, code, issues, and suggest the best package.
