About Me

I'm a final-year Information Technology student at Hanoi Open University, expected to graduate in June 2026. My focus is backend engineering — not just following coursework, but independently designing real production systems.

I build with Java 21 & Spring Boot 3 as my primary stack, with additional experience in React, TypeScript, C# and Python. I care deeply about clean architecture, query performance, and security — JWT token rotation, Optimistic Locking for concurrent access, and fixing N+1 problems before they hit production.

Beyond code, I've tutored 10+ students in Data Structures & Algorithms, which sharpened my ability to explain complex systems clearly — a skill that matters in any engineering team.
