About Me
"To obtain a Backend Developer position where I can utilize my technical skills to contribute to the company's success while continuously learning and growing as a developer."
I'm a 2003-born developer from Hanoi, currently graduating in Information Technology from Thuy Loi University. My journey began with .NET Core and has expanded to Go, Laravel, and full-stack development.
I specialize in database engineering and performance tuning — reducing query latency by 75% for datasets of 1.5M+ records. I'm passionate about clean architecture, SOLID principles, and leveraging AI agents to optimize coding workflows.
