Marketplace · SSR

Background

Specialised in the hard parts of frontend.

I build the surfaces that handle the most traffic, the most complexity, and the highest stakes. At Poshmark, that means marketplace discovery for 130M+ users, real-time live commerce, and platform infrastructure — the kind of work where a 100ms regression costs conversion and a broken SSR page reaches millions.

Outside of work I build tools I actually use — a news reader, a private diary, a colour system generator. These projects let me go deeper on state architecture, local-first data, and editorial UX without the constraints of a production codebase.

I care about the craft at every scale — from component API design to page load budgets.
