AI features inside an institutional investment platform

AI touchpoints across an institutional platform — a composer in the dashboard and contextual AI inside reports, documents and meeting notes. Streaming, inline editing, agent handoffs and human-in-the-loop review, specified state by state.

Capacity matching for private truck fleets

A design sprint produced a platform. A comparison test with six people from fleet teams said the plain email it was meant to replace was the better bet. We shipped the email — response rate up 250%.

A design system a whole team can build from

Two sources of truth and neither matched what shipped. One canonical source, eight rule families written to pass or fail, and a register that routes anything drawn from scratch to review. 48 components, 9 templates.

Looking for someone who ships the whole thing?

Open to senior, lead and founding design roles, or consulting. Design that ships with engineering, not alongside it. Remote, happy to travel. Tell me what you are building and I will tell you honestly whether I am the right person for it.
