Welcome to my GitHub profile! I'm a passionate Android engineer and architect with 10+ years of experience building production mobile systems across robotics, EV infrastructure, fintech, e‑commerce, and real-time streaming. I design scalable architectures, lead cross-functional teams, and ship apps that millions of users rely on.
- 🔭 Currently — Tech Lead at Tadafuq, architecting a full-stack EV Charging Management Platform (Python/OCPP, Node.js WebSocket, Flutter) and shipping Mega Plug on Google Play & App Store.
- 🤖 NEOM & robotics — Built Android experiences for CRUZR and Pepper humanoid robots at NEOM City; integrated GPT-4 for intent recognition (~35% fewer escalations to humans).
- 📱 Scale — 120k+ MAU on a live auction platform with WebRTC + ExoPlayer; sustained 99.9% crash-free production builds across releases.
- 🏗️ Leadership — Led 4–6 engineers; introduced ADRs, code review standards, and MVVM + Clean Architecture migrations (15+ feature modules).
- 🌍 Domains — Smart cities, EV/IoT, marketplaces, banking wallets, health/pharmacy, e‑commerce, Android TV.
- 💡 Always learning — Blockchain/Web3, system design, Flutter, and iOS essentials.
