About Me

I'm an AI-focused Senior Android Engineer with 9+ years of experience building scalable, production-grade mobile apps that have crossed 10M+ combined downloads — for companies like UNFPA, UNICEF, Walmart, Cisco, Vahak, GimBooks, and more.

My sweet spot is where Android meets AI: integrating on-device ML (Gemini Nano), LLM APIs, and AI SDKs like Soul Machines' Autonomous Digital People into real products. I obsess over clean architecture, performance, and shipping features that move metrics — 20% performance gains and 25% crash reductions along the way.

I love owning products end-to-end, mentoring teams, and shipping with 90% crash-free sessions. I've thrived in both fast-paced startups and enterprise environments — solo-building MVPs from zero, and today leading Android projects and teams on products used by millions.

Currently seeking AI-integrated Android Lead roles — also open to remote / hybrid opportunities.
