I will fix, complete and scale your vibe coded mobile app
Hamza
About this gig
Did your Flutter app start with AI tools, vibe coding, FlutterFlow, or another developer and now it is difficult to fix, complete, or scale?
I will audit, fix, complete, and improve your existing AI-generated or half-built Flutter app for Android and iOS.
This gig is for startup founders and businesses with an existing Flutter codebase that has become unstable, incomplete, slow, or hard to maintain. I will first understand the issue, then fix the agreed scope with clean, maintainable code.
I can help with:
- Flutter bugs, crashes, build errors, and dependency conflicts
- AI-generated or vibe-coded code cleanup and refactoring
- Incomplete screens, flows, and features
- Firebase, API, authentication, and state-management issues
- Performance improvements and UI fixes
- Android/iOS build and release-readiness support
Please message me before ordering with your repository/ZIP file, issue screenshots or video, error logs, and top priorities. For large or unclear codebases, I will review the scope and send a custom offer.

FAQ
My app was built with AI tools, FlutterFlow, Cursor, Claude, ChatGPT, Copilot, or another freelancer. Can you work on it?
Yes. I can review and improve existing Flutter projects created with AI tools, FlutterFlow exports, rapid-prototyping tools, or another developer—as long as you can provide the complete source code and any required access. Please message me before ordering so I can confirm the scope.
Can you fix all bugs and complete my entire app in the Basic package?
No. The Basic package is for one clearly defined issue only, such as a crash, build error, broken API call, UI issue, or dependency conflict. If your app has multiple bugs, unfinished features, or architecture problems, please contact me first for the Standard, Premium, or a custom offer.
Can you make my Flutter app stable and ready to scale?
Yes. For suitable projects, I can refactor agreed modules, improve app structure and state management, resolve Firebase/API issues, optimize performance, and prepare Android/iOS release builds. The exact work depends on the existing codebase, so a review is required before confirming a larger scope.
Can you publish the fixed app to Google Play or the App Store?
I can prepare the Android/iOS release build and guide you through submission using your own Google Play Console and Apple Developer accounts. Store approval is controlled by Google and Apple and cannot be guaranteed.
Can you help me publish my rescued app to the App Store and Google Play?
Yes, I can! Once we fix AI code errors and stabilize your application, I can help you configure your developer certificates, prepare the deployment release, and navigate the submission process for Google Play and the Apple App Store.
