About this Gig
Is your app crashing, slow, failing to build, or rejected by the App Store or Google Play?
I fix mobile app bugs, crashes, API issues and store rejections fast, so your users stay happy and your app gets back on track. I find the root cause, fix it properly and explain what went wrong.
I can fix
- App crashes, freezes, red screens and runtime errors
- Build failures: Gradle, CocoaPods, Xcode and package errors
- API, backend, Firebase and Supabase integration issues
- App Store and Google Play rejections, then resubmit your app
- Slow screens, lag, memory leaks and large app size
- Outdated packages, SDK upgrades and broken AI-generated code
Apps I work on
- Flutter and FlutterFlow apps
- Native Android (Kotlin, Java) and iOS (Swift, Objective-C)
- React Native apps
- Backend APIs (Laravel, Node.js, Firebase, Supabase)
What you get
- Root-cause fix, not a quick patch
- Tested build on Android and iOS
- Short report of what I fixed
