Portfolio

Things I have built, and helped build.

Some of this I built and run myself. Most of it I worked on as a freelancer or partner inside a delivery team, so it is team work, not solo work. Client names are left out on purpose, because most of it is under NDA. Ask me about any of it on a call.

What I specialise in

AI personal assistants for founders.

I build personal AI assistants on Instinct, GrokBot and Hermes, set up around how a founder actually works: their inbox, calendar, tools and the jobs they keep doing by hand.
