About Me
"Software Engineer with experience developing ERP systems, RESTful APIs, internal business applications, and AI-powered document search platforms. Skilled in ASP.NET Core, SQL Server, PostgreSQL, Docker, and modern software development practices."
I'm a 2003-born developer from Hanoi, currently graduating in Information Technology from Thuy Loi University. My journey began with ASP.NET Core and has expanded to FastAPI, Laravel, Spring Boot, and full-stack development.
I specialize in database engineering and performance tuning — reducing query latency by 75% for datasets of 1M+ records. I'm passionate about clean architecture, SOLID principles, and building end-to-end solutions from database design to deployment.
