About this gig

Your app is crashing. Users leave bad reviews, launch day slips, and every hour costs you money. I know that stress, and I can take it off your shoulders.


I'm a Flutter developer and React Native dev. I do app bug fixing for apps that are not working. I find the real cause and fix it so it stays fixed.


What I Offer:

  • App crash fix and fix app crashing
  • Flutter bug fix and Flutter app fix
  • React Native bug fix
  • Android app fix and iOS app fix
  • App error fix and app debugging
  • Slow or frozen screens
  • Login, API and Firebase problems
  • Build errors
  • Mobile app fix and Play Store or App Store upload


How I work:

I reply fast, explain the cause in plain words, and test on real devices. Your code stays yours and stays private.


Message me first with your error or a screenshot. I will tell you honestly if I can fix it.


Let's get your app working again.
