Android Developer&&Reverse Engineer
I build native Android apps in Kotlin — and take APKs apart to understand exactly how they work.

I contribute fixes to open-source Android projects and lead the Android track at GDG JSS.
.section 0x01 projects
Android apps, an SDK and on-device ML, each designed and built end to end.
0x01· Voice-first AI wellness companion
Detects early burnout from a two-minute daily voice check-in. Built solo for the AI Mobile Hackathon 2026.
0x02· On-device face clustering from video
Processes a portrait video fully offline, finds every distinct person, counts their appearances and renders a shareable collage.
0x03· Crash analytics SDK
An Android library that ships the timeline of user actions leading up to a crash — so you can reproduce it instead of guessing.
0x04· Trading strategy backtester
Replays 20+ years of market data candle by candle to test RSI and moving-average strategies against the S&P 500.

// → signature 0x5f3a…c91b · gasless ✓0x05· DAO governance on Android
A native client for browsing and voting on Snapshot proposals from Uniswap, Aave and ENS.
0x06· Real-time multiplayer game
An Among Us-style Android game — live movement, kills, body reports, meetings and tasks, synchronised over Socket.IO.
.section 0x02 reversing
I learn how Android apps really work by taking them apart — decompiling, reading and patching Dalvik bytecode, and hooking code at runtime. My practice follows the OWASP MASTG crackmes.
Decompile with JADX, trace the verify path and recover the AES/ECB-encrypted secret from the key and ciphertext.
Read Dalvik bytecode at the register level, follow control flow, and understand how root and integrity checks are implemented.
Inspect behaviour at runtime with Frida and ADB, and do basic inspection of native .so libraries.
