Outside work

Anything that gets me moving. Parkrun on Saturday mornings, long rides through London, and bouldering at The Castle. If I'm not on an adventure, you'll find me trawling through Rough Trade for something worth taking home, playing guitar, or disappearing into a good film. I love to travel, see the world, and meet people. Trying to hone my craft in the kitchen too. And when I'm at home I'm usually building something — a home media server, scripts to organise years of photos, tools to speed up my workflow. Code as a creative outlet as much as a professional one.
