_software developer · leeds, yorkshire

Hey, I'm Tom.I build things.

Software developer in Leeds, Yorkshire, nearly four years in from a standing start. This site is where I experiment and crash things, and every version I've ever shipped still runs.

See the projects Commercial and client work

Everything here I built because I wanted to. The paid work is over there.

Proof, not promises

The clearest way to judge whether I can build things is to read how I built one.

Ever since I watched The Matrix as a kid, I've been obsessed with building things on the web. This site is the sci-fi playground I always dreamed of, a space to experiment with AI, cyberpunk aesthetics, and creative code.
