obsessed with edge compute and collaborative editing.

ABOUT
─────────────
Seven years building production systems that handle traffic spikes with grace
and developers with patience. Led the real-time collaboration engine at
Notion-scale, shipped WebSocket infrastructure serving 2M concurrent
connections, and still find time to maintain three open-source libraries. I care
about latency, accessibility, and writing code that the next person can actually
read.
