I will fix bugs, crashes and performance issues in your flutter app
About this Gig
Is your Flutter app crashing, lagging, or misbehaving? I fix it fast.
I'm Mahmoud, a Flutter developer who has spent the last few years maintaining a live, production ride-hailing platform that has completed over 500,000 real trips. I don't just write code, I debug apps that real users depend on every day, under real-world conditions like flaky networks, GPS edge cases, payment failures, and high concurrency.
What I can fix:
- App crashes and freezes
- - UI bugs and broken widgets
- - State management bugs
- - Firebase issues (Auth, Firestore, FCM)
- - REST API and Socket.IO bugs
- - Performance issues and memory leaks
- - Google Maps and location tracking bugs
- - Payment gateway issues
How I work: send me your source code, a clear bug description, and steps to reproduce it. I find the root cause, fix it, test on real devices, and explain what was wrong.
Message me before ordering so I can confirm scope and timeline.

FAQ
Do I need to send you the full source code?
Yes, please share your repository (GitHub/GitLab/zip) along with a clear description of the bug and steps to reproduce it. I'll never share or reuse your code.
What kind of Flutter apps have you worked on?
I've spent the last few years building and maintaining a live ride-hailing platform (rider + driver apps) with real-time GPS, payments, and Socket.IO, now used for 500,000+ completed trips.
