Data sheets
A bulk import system that turns messy grant spreadsheets into validated, committed records, with AI-assisted column mapping that suggests but never decides.
David Townsend
Design engineer. I take product problems from the first conversation to the fifth iteration: research, prototype, backend, frontend, release plan, and the tooling the team needs along the way.
For more than ten years I have worked on Vestd, the UK's leading equity management platform, joining as a founding engineer, spending three years as its founding product designer, and now owning big feature projects end to end as a full-stack design engineer. I like complex domains, small teams, and the breadth that comes with owning the whole problem.

2026
Investment rounds
A redesign of how companies run an investment round, where legal documents fall out of the decisions people make instead of being edited by hand, and a non-linear process still feels guided.
