About

The story so far.

Frontend engineering leader with 10+ years of experience building React-based UIs, design systems, and component libraries. I specialise in translating high-fidelity design mocks into scalable, accessible, and performant interfaces.

I care deeply about the intersection of engineering and UX — the kind of work where clean code and thoughtful design meet. I've spent my career collaborating closely with product and design teams to get that balance right.

Outside of work, I build side projects that scratch my own itch — from AI-powered web apps to developer tooling. If there's a problem worth solving, I'll find a way to build it.
