The person behind the work

Who I am

I'm a full-stack developer from Cambodia. I build web apps with Spring Boot, Next.js and PostgreSQL.

My approach

I like clear structure on both sides: well-designed REST APIs with proper authentication, and simple, responsive interfaces on top. I pick things up quickly and use modern AI coding tools to move faster without cutting corners.
