About

I work end to end: architecture, implementation, deployment, and the operational tail that follows. For the past few years I've been the sole developer on a suite of products, which means every decision — schema, queue topology, CI, the interface — has been mine to make and mine to live with.

Recently that's meant applied AI on infrastructure companies can host themselves: retrieval over private document corpora, PII redaction that runs locally before anything reaches a model provider, and agents that act in Microsoft 365.

Stargazing, hiking and travelling. Rally and motorsport, closely followed. Strategy and simulation games — for the same reason I like the day job: a system worth taking apart.
