About this gig

Is your Android app crashing, freezing, or misbehaving? I'll find the bug and fix it cleanly and fast.


I'm an Android developer who builds and ships real apps in Kotlin. My own game "Ragnarok Rush" is live on Google Play (100+ levels, in-app purchases, ads), so I know how to read real codebases and squash real bugs.


WHAT I DO:

Fix crashes, ANRs and freezes

Fix UI, layout and logic bugs

Fix Gradle / build errors

Jetpack Compose issues

Add a small feature or improvement

Performance optimization


YOU GET:

A clean, tested build that actually works

Full source code

A short explanation of the cause


WHY ME:

I ship finished products, not half-done demos

Fast, clear communication

Clean, maintainable code


Message me BEFORE ordering with a short description of your bug (and your code if possible) so I can confirm the scope and give you an honest timeline. Let's get your app working!
