SET IN BASKERVILLE · ALIGNED TO A 14PT BASELINE GRID

I design and build software end-to-end — web apps, data tools and AI services that people actually enjoy using. Currently building at Sourcerie, where the work runs from database schema to interface polish, with everything in between.

Sourcerie. Product engineering across a B2B platform — React, Node and Postgres, plus all the glue in between. Full-stack in the honest sense.

Notes. An AI note-generation service on Cloudflare Workers: queues, KV, R2 and a deliberately tiny interface.

Ask the data. Natural-language analytics. Plain-English questions in; carefully compiled SQL out.

Correspondence. Letters to the editor are warmly received — GitHub, LinkedIn, or the classic: get in touch.
