👨‍💻 About

Professional

Staff/Lead-level mobile engineer with 10+ years of experience shipping production-grade Android and iOS apps for fintech, e-commerce, advertising, and transport.
Focused on composable architectures, team mentorship, and clean, testable code that scales.

Personal

Husband. Dad. Explorer.
When I’m not shipping mobile features, I’m outside with an 8-inch Dobsonian telescope watching Saturn’s rings or planning the next family trip with my camera in tow.
I read philosophy and anything that stretches my thinking.
I run a small Airbnb and a laundry venture practical experiments on the road to financial independence.
Fitness keeps me honest; curiosity keeps me moving.
