01 / about $ cat ./about.md

Senior full-stack
engineer, with a designer's
eye for what ships.

Sawad-dee — I'm Oat. Senior full-stack developer based in Bangkok with 8+ years building production web applications. Currently at WHA Group working across cloud and container environments — Docker, Kubernetes, Huawei Cloud.

My work spans document management, BPM, graph & reporting dashboards, and backoffice web apps — systems where reliability and UX both matter. I've led front-end architecture and owned full-stack delivery across every level of seniority.

I hold a Master's in AI for Business Analytics from KMITL and a B.Sc. in Computer Science from RMUTT. My focus is shifting toward Machine Learning, LLM applications, and AI Engineering — building intelligent systems on top of solid engineering foundations.
