About this Gig
Your app is live but it's not performing. Maybe it crashes on certain devices. Maybe it's slow to load. Maybe users are leaving bad reviews about bugs you can't seem to track down.
I fix broken apps. Fast.
Here's what I'll do:
- Diagnose and fix crashes and ANRs (App Not Responding errors)
- Optimize app startup time and screen load performance
- Reduce memory usage and eliminate memory leaks
- Fix UI jank, stuttering, and frame drops
- Resolve platform-specific bugs (iOS vs Android inconsistencies)
- Clean up legacy code and improve architecture
- Upgrade outdated dependencies and Flutter SDK versions
- Review and improve your app's overall stability
I'll deliver a detailed report of every issue found and fixed, plus recommendations for preventing them in the future.
Packages:
- Basic: Bug diagnosis and report I'll find the issues and tell you exactly what needs fixing
- Standard: Fix up to 5 specific bugs or performance issues with code delivery
- Premium: Full app audit, all bugs fixed, performance optimized, code cleanup, and stability report
Send me a description of what's going wrong, and I'll give you an honest assessment of what it'll take to fix it.

FAQ
What if you can't reproduce the bug?
I'll ask for crash logs, user reports, device models, and OS versions. Even intermittent bugs leave traces. If I genuinely can't find it, I'll tell you honestly and we'll adjust the scope.
Do you need access to my app's source code?
Yes. I'll need access to your GitHub, GitLab, or Bitbucket repository. I sign NDAs if needed — just mention it when you message me.
My app is built with React Native / Swift / Kotlin — can you still help?
My expertise is all around mobile development. If your app is built with a mobile framework/language then most likely yes. Message me first and I'll let you know if I can help or point you to someone who can.
How do I know the fixes actually worked?
I provide before/after metrics: crash-free session rate, startup time, memory usage, frame rates. You'll see the numbers improve.
What if fixing one bug creates another?
That's what the revision rounds and post-delivery support are for. I test thoroughly before delivery, but if something slips through, I fix it at no extra charge within the support window.
