About

I build logistics software at Certu Systems in Bangkok — Go services on the backend, the mobile app up front. Before that I packaged a big-data platform for Kubernetes, built CI/CD pipelines, wrote end-to-end test suites, and spent three years as a teaching assistant across five computer science courses at Mahidol University. I like scalable systems, hard problems broken down properly, and teaching what I learn along the way.
