About Me

About me
3.0 GPA / 4.0

I am a fourth-year student majoring in Software Engineering (Information Technology) at Saigon University (September 2022 - March 2027). I am passionate about building reliable, secure, and scalable backend systems.

I enjoy learning software architecture, integrating APIs, and deploying applications with Docker. My current goal is to find an internship where I can contribute to real projects and grow quickly.
