About Ruitan

Portrait of Ruitan HuangI'm Ruitan Huang, a product and systems designer. I design whole systems, and the AI that works inside them, then build and ship them.

Samsby is the largest: one system for a trade business, from Sam, the AI receptionist that answers the phone, to enquiries, jobs, quotes, invoices and follow-ups that AI drafts and the owner sends. Velochat and LiftGauge bring real-time chat, sync and offline use to riders and lifters. The longer story is on its own page.
