I will do flutter bug fix and mobile app maintenance
Flutter Mobile App Developer
About this Gig
Need a fast Flutter bug fix or ongoing app maintenance to keep your app running smoothly?
I'm a Flutter developer with 6+ years of experience and 12+ production apps, including apps with 100K+ active users. I've debugged crash reports, fixed performance issues, and kept live apps stable for real paying users, not test projects. I can work directly in your existing codebase, whether I built it or another developer did.
What I can fix:
- Flutter bugs and crashes on Android and iOS
- Performance issues: lag, memory leaks, slow load times
- Firebase or Supabase integration errors
- UI glitches and layout bugs across screen sizes
- App Store or Google Play rejection issues
- Compatibility problems after OS, package, or Flutter SDK updates
Every fix comes with a short report explaining what was wrong and what I changed, so nothing is a black box. Send me your error logs, crash reports, or a quick description of the issue, and I'll reply with a diagnosis and fix plan within a few hours.

FAQ
Do I need to send you my full source code?
Yes, I'll need access to your Flutter project (GitHub, GitLab, or a zip file) to diagnose and fix bugs accurately.
What if the bug isn't fully fixed after delivery?
Each package includes revisions specifically for the reported bug at no extra cost, until it's resolved.
Can you work with an app another developer built?
Yes, I regularly take over and debug existing Flutter codebases, not just my own builds.
Do you sign an NDA?
Yes, happy to sign one before you share your code if needed.
What's included in the 30-Day App Care Plan?
Unlimited priority bug fixes, proactive crash and performance monitoring, and a weekly status update for 30 days.
How fast can you respond to an urgent bug?
Message me with the issue and I'll confirm a diagnosis timeline, typically within a few hours.
