About this Gig

Your React Native or Expo app crashes, the EAS build suddenly fails, or App Store review keeps rejecting it? I find the cause and fix it.


I design, build and maintain 9 live apps of my own, shipped in 175 countries. SDK upgrades, EAS builds, in-app purchases, widgets and review rejections are my everyday work.


What I fix

  • iOS / Android build failures (EAS, Xcode, Gradle)
  • Crashes, slow screens and memory issues
  • Breakage after Expo SDK or React Native upgrades
  • App Store / Google Play rejections and resubmission
  • In-app purchases (RevenueCat), push notifications, sign-in


Before starting I review your code and tell you honestly whether and how it can be fixed. Every fix comes with a short change log.
