About this gig

Is your React Native app crashing, slow, or broken on iOS or Android?

I fix it fast. I manage a live app with 200,000+ active users performance and stability are things I deal with in production every day, not just in tutorials.

WHAT I FIX: Crashes and runtime errors Slow screens and janky animations Memory leaks and high CPU usage iOS and Android build errors Navigation and state management bugs Firebase and API integration issues TypeScript and lint errors App Store and Play Store rejection fixes

WHAT YOU GET: Root cause identified, not just patched Clean fix with explanation of what was wrong Tested on iOS and Android before delivery Full source code returned

HOW IT WORKS:

  1. Share your code and describe the issue
  2. I review and send a diagnosis within 24 hours
  3. We agree on scope and timeline
  4. Fix delivered with clear explanation

MESSAGE ME FIRST share your issue and I will tell you honestly if I can fix it before you order.

I manage a live fintech app with 200,000 active users across iOS, Android and Huawei AppGallery. Not a tutorial project. Real users, real money, real production. Most clients come to me after a developer delivered something that broke in production. I build apps that scale from day one. I specialize in fintech, EdTech, and business apps with Apple Pay, biometric auth, AES encryption and jailbreak detection built in. Message me for a free project plan within 24 hours.
