Maya Chen

Full-Stack Engineer

I build the plumbing nobody sees and the interfaces everybody does. Currently 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.
