04About

Building software, leading people, and teaching along the way.

Since 2020 I have shipped fintech, blockchain, communications, esports, and education products. These days I lead a frontend team at Code Of Us, keep a hand in the full stack, and treat AI coding agents as part of a professional engineering practice — not a shortcut around it.

Mentorship, workshops, and 1-on-1s sit alongside delivery. The work is the product and the team that can keep shipping it.
