About

Engineer first, partner throughout.

I've spent eight years building for the web — most recently as a Senior Software Engineer at AnyVan and before that as a Tech Lead at Dunelm, where I led a cross-functional team of twelve and was recognised with the 2024 Mentorship Award.

Alongside that I take on a small number of consulting projects: complete sites for independent businesses, product builds, and technical strategy. Same standards either way — measured, documented, shipped.
