01 About

Design Engineer who ships the whole thing

I solve the problem that sits between design and engineering - the gap where intent leaks and builds drift from what was designed. Over the last five years I've done that as a Design Technologist at a global fintech, as a founder shipping a live product, and as someone who builds the tooling that lets teams ship faster.

I work with AI-assisted development systems. Agents draft, custom review gates check, and the human owns taste and judgement. I'm a passionate believer that human and machine work fastest together.
