About
Mathematician by training, builder by habit.
I studied mathematics and statistics in London, spent a year teaching frontier models what good answers look like, and now design and ship AI products for a sportswear group and my own startup. I care about systems that explain themselves, and the unglamorous integration work that makes them run in production.

Looking for: a Forward Deployed Engineer role where I embed with customers and take frontier-model systems to production. Based in London, open to relocation.
Building: Kelay AI, a voice receptionist for small businesses, and the enterprise version of GAIMS.
Writing next: how I design rubrics for LLM evaluation, from a year of RLHF rubric work and a 15-person review team.
Open source this quarter: a webhook intake kit (HMAC, idempotency, outbox), an auditable LLM decision ledger, and a voice-agent starter.
