About

Software Engineer at Certu Systems and Computer Science graduate from Mahidol University. I work across the stack — from Go backends and mobile apps to Kubernetes, CI/CD, and end-to-end test automation. I enjoy building scalable systems, breaking down hard problems, and teaching what I learn along the way.
