I build practical software around AI, data, analytics, and adtech.
My work sits between product thinking and implementation, with a bias toward systems that make real work less messy.
Based in London. Interested in useful AI, clearer measurement, and software that holds up outside a demo.

Notes from the work
From idea to live website: the agent-friendly shipping guide
A plain-English guide for anyone who has an idea and a coding agent but no infrastructure experience — jargon explained, tokens stored safely, AGENTS.md doing the operational lifting, and a vendor-neutral way to ship a live website.
How Google Ads Cross-Account Conversion Tracking Credits the Right Account

Have something useful to build?
I am always interested in thoughtful software, analytics, and AI work where the practical details matter.
