03 / About

Frontend, for systems where reliability isn't optional.

I'm a frontend engineer based in Chiang Mai, Thailand, with over a decade of experience building interfaces for institutional finance. I've spent most of that time at LSEG and Refinitiv, working on real-time systems where a stuck WebSocket is a P1.

Outside of code, you'll find me in the kitchen making homemade Greek yogurt with my wife.
