About this Gig

Hi! I'm a senior native Android engineer specialized in fixing bugs and maintaining existing apps. Whether your app crashes, has UI glitches, performance issues, or breaks on new Android versions, I can diagnose and fix it fast.


What I fix and maintain:

  • Crashes, ANRs and hard-to-reproduce bugs
  • - UI and layout issues across devices and Android versions
  • - Performance, memory leaks and slow screens
  • - API, networking and database problems
  • - Library and Gradle upgrades, deprecated code
  • - Play Store rejections and compliance issues

How I work:

  • I reproduce the issue, find the root cause and fix it properly (no quick hacks)
  • - Clean Kotlin/Java code, tested before delivery
  • - Clear explanation of what was wrong and how I fixed it

Send me a message with your app details and the bug before ordering so I can scope it correctly and pick the right package.
