Is your Android app crashing or misbehaving? I'll find the bug and fix it — fast and clean. Native Android development in Java and Kotlin, 8+ years of experience, banking apps with 100K-2M+ users. What I can do: fix crashes (NullPointerException, ANRs), UI glitches, unexpected behavior; resolve issues with APIs, Firebase, Room, Retrofit, third-party SDKs; add new features or small modules; clean up messy code. Same chat-only process: describe the bug, share code access, I reproduce and confirm scope, then fix, test, and summarize.
