Über diesen Service

Existing app crashing, broken, or stuck? I'll diagnose and fix it no full rebuild needed.

I fix bugs, crashes, and performance issues in Android (Kotlin/Java), Flutter (Dart), and Kotlin Multiplatform codebases including apps I didn't originally build.

I fix:

  • App crashes and ANRs
  • UI bugs and layout issues
  • Memory leaks and performance problems
  • Build/Gradle errors
  • Broken API or Firebase integrations
  • Play Store/App Store rejection issues

What you'll get:

  • Root cause diagnosis
  • Fixed, tested code
  • A short summary of what was wrong and what changed

Send me your repo access, error logs, or a description of the issue, and I'll confirm scope before you order.
