About

David is a programmer drawn to the theory as much as the craft — functional programming, type systems, and language design. His public work leans heavily on Rust and low-level tooling, with a taste for the tacit, point-free style that says more with less.

He is a cadet at 42 and writes about the ideas he's chasing — monads in Rust, PL exploration, and the occasional yak-shave — on his blog, davidLee >>= blog. As CTO of Prism Labs he leads engineering on Toggle AI: the Angular + signals frontend, the Bun / Elysia / Drizzle backend, and the AWS infrastructure behind it.
