Crashes, broken flows, API integration problems, Room/database issues, UI bugs in Jetpack Compose or XML layouts. I build production Android apps in Kotlin (MVVM, Coroutines/Flow, Retrofit, Room, Hilt) and can reproduce, isolate, and fix the issue in your codebase, with a clear explanation of the root cause. You get: the fixed code (PR or patch), a root-cause note, and the exact places changed. NDA-friendly; your code stays yours. Rules: escrow funded before work starts; repo access via GitHub (krishpro14) after escrow; scope = one defined issue per gig.
