About

A decade of shipping software that matters.

From building fleet management systems at my first job to architecting AI-powered government platforms at scale — every line of code has been about making complex systems work seamlessly for real people. I've shipped production software used by national government institutions, internationally funded research programs, and enterprise clients across Southeast Asia.
