About this gig

Your React Native or Expo app crashes, shows a white screen, or refuses to build, and you have already spent hours on it.


WHAT I FIX

White screen on launch, crashes on startup

Build failures: Gradle, EAS, Xcode, Metro bundler

Native module errors after installing a package

Push notifications not arriving on iOS or Android

Google or Apple Sign-In not working

Works in Expo Go but breaks in the production build


HOW IT WORKS

Send me your error log or a screenshot before ordering

I confirm I can fix it and quote a price

You get working code plus a short written explanation of what was wrong


WHY ME

I work on a production app published on the App Store and Google Play, so I know the difference between it runs on my machine and it survives release. I have taken an app through three Apple review rejections to approval.

I build and rescue digital products. I shipped a marketplace app to the App Store and Google Play, run its backend on my own server and built its website. So I have already hit the problems that stop most projects: crashes, failed builds, store rejections, subscriptions that break on renewal. I also cover UI design, AI video and automation, so a small team gets one person instead of four. Tell me what is broken or what you need built. I will tell you honestly whether I can do it.
