Who is Jack Stovell?

Jack Stovell is a solo AI developer in London. He builds and runs a one-person software studio, Adapt Progress Evolve Limited, registered in England and Wales as company number 10047328 (Companies House record), registered office 5 Brayford Square, London E1 0SG, VAT GB362654684, and publishes his code as github.com/StovBuilds. The products below are built and operated with a fleet of 28 Claude agents doing the building, checking and day-to-day running, and nothing ships without his approval. That fleet is called Jarvis, and it is written up post by post in the Jarvis architecture series. This site is his personal blog: notes on building solo with AI, for other solopreneurs and developers.
