About

I'm Christian Haddrell — a senior product engineer based in the UK. I've spent years shipping software end to end, and I now work through Dougal Debug Limited, helping teams ship faster with agentic tooling rather than despite it.

This site is for essays on engineering judgement, and occasional write-ups of personal builds. I don't write about client work — out of respect for confidentiality, anything here is either a personal project or an anonymised observation.
