Hello! I am an experimental physicist by trade, and a hobby programmer. I live in London with my wife and dog. Contrary to what some weird little guys may claim, London is a wonderful city to live in.

You can reach me at me@spxtr.net, spxtr on Libera chat, or @spxtr@floss.social.

Here are some projects I've worked on:
