I design and build things that try to be useful for a long time.

I’m a design engineer based in London. I work in the seam between product design and frontend engineering — the parts where a design system, a real database, and a clear point of view have to agree with one another.

Most of the last decade has been spent inside product teams at Sage, Selfridges, End Clothing, and Rosetta AI, building software for people who don’t care what stack it’s on. I tend to gravitate toward design systems, internal tooling, and the unglamorous flows that quietly carry a product.

Outside client work I’m building Ragnar, an open design system, and shipping small Figma plugins — FigQA and Varvx — that fix the parts of the design tool I keep wishing were different.

I take on a small number of design engineering and product strategy engagements each year through Nordlean. If you’re building something that involves design systems, design tooling, or the early shape of a new product, I’d like to hear about it.
