Tuan.
Software Engineer with hands-on experience in containerized infrastructure, CI/CD pipelines, and production deployment on Linux servers — building reliable backend systems and getting them running in the real world.
About Me
"I build backend systems and make sure they actually run in production — containerized, automated, and maintainable."
I'm a 2003-born developer from Hanoi, graduating in Information Technology from Thuy Loi University. I started with ASP.NET Core backend development and gradually picked up Docker, CI/CD, and Linux server deployment as my projects grew more complex.
My sweet spot is the intersection of backend engineering and infrastructure — designing services, containerizing them, setting up deployment pipelines, and keeping things running on a Linux server. I'm currently deepening my DevOps skills while staying grounded in solid backend fundamentals.
