About

I am a Computer Science Engineer with a solid foundation in software development and a deep passion for applied research. I'm drawn to problems where rigorous engineering meets systems that think — building things that don't just work, but understand.

My path into computer science began at Can Tho University, where I completed my degree in Computer Science Engineering. Along the way, I built a solid foundation in algorithms, software design, and systems thinking, while developing a growing curiosity for how intelligent systems are built and applied to real-world problems — a curiosity that has only deepened with every project since.

My career direction centers on three areas I find genuinely compelling: Artificial Intelligence, Robotics, and Financial Technology. I'm drawn to problems where intelligent systems meet real-world deployment — whether that means building machines that can perceive and act autonomously, or applying data-driven models to solve practical challenges in finance. I bring both engineering discipline and a research-minded curiosity to my work, always looking to understand not just how something works, but why it works that way.
