Acerca de este Servicio
Is your Flutter app crashing, glitching, or running slower than it should? I'll find the problem and fix it clean, tested, and ready to ship.
I'm a Flutter developer with 4+ years of experience building and maintaining production apps for Android and iOS, with a combined 600K+ downloads across fintech, healthcare, aviation, and wellness apps. I work daily with GetX, BLoC/Cubit, Clean Architecture, and Firebase, so I can move quickly through your codebase without breaking what already works.
Common issues I fix:
- App crashes, freezes, or laggy performance
- API or Firebase issues (data not loading, sync errors, etc.)
- Navigation and routing problems
- Compatibility issues after SDK updates
- UI glitches and broken widgets
- Slow load times and memory issues
Why work with me:
- Fast, honest communication I'll tell you clearly if something needs more time or scope
- Clean, maintainable fixes, not quick patches that break later
- Experience across real, shipped apps in demanding industries (fintech, healthcare)
- Source code included with every order
Send me your bug details and, if possible, access to your project (ZIP or GitHub), and I'll take it from there.

FAQ
What Flutter bugs can you fix?
Crashes, UI glitches, navigation issues, Firebase/API errors, performance problems, and compatibility issues after SDK or package updates. If you're not sure your issue fits, message me first and I'll confirm before you order.
How should I describe my bug?
Tell me what's broken, what you expected to happen instead, and the steps to reproduce it. Screenshots or a short screen recording help a lot and often speed up the fix.
Can you work with my existing codebase?
Yes. Send a ZIP file or GitHub access (read or collaborator access), and I'll review the relevant code before starting so there are no surprises on scope.
Do you provide the fixed source code?
Yes, full source code is included in every package.
What if my project needs more than 5 bug fixes or has a larger issue?
Message me with the details first. If it's a bigger job, I'll either scope a custom offer or point you toward my other gigs for larger builds or refactors.
