I make tools I wish existed — and write down what breaks.
Senior software developer at QoQa 🦦, currently shipping iOS & web products that earn their keep.
Over the years I’ve built products for QoQa, Pix4D, Zip, and the BBC — learning by building, breaking, and refining. On the side I make tools I wish existed, and outside of code it’s self-hosting, hardware tinkering, and too much football.
Things I’ve learned, written down.
An AI agent in my homelab
An agent in a container that helps run the house — what it does, and the fences that make me okay with it.
HTTPS for services the internet can't reach
A home lab isn't publicly reachable — DNS-01 and a wildcard cert fix it in one line of Caddy, plus the renewal gotcha.
A DNS server for the house — and why Technitium
What your own resolver actually buys you — and why Technitium over the usual stack.
Tools I make for myself, and share.
