I build resilient distributed systems and the interfaces that make them feel effortless.

For the past eight years I have worked across the stack — from kernel-adjacent performance work to design-system-grade frontend — at companies shipping to millions of users.

I care about the seams: the boundary between systems is where reliability is won or lost, and where good engineering quietly compounds.

Lately I work mostly in TypeScript, Go and Rust, with a soft spot for edge runtimes, observability, and tools that shorten the loop between an idea and a deploy.
