Java Backend Developer
I build reliable backend applications with Java, Spring Boot, RESTful APIs, and relational databases.
Building a strong foundation in backend engineering.
I am a Computer Science student at Hanoi University of Science and Technology, pursuing a career in Java Backend Development. I enjoy turning business requirements into structured, maintainable applications and learning how reliable backend systems are designed, secured, and deployed.
Through academic and personal projects, I have worked with Spring Boot, Spring Data JPA, Spring Security, JWT authentication, PostgreSQL, MySQL, RESTful APIs, and React. I am currently strengthening my knowledge of Docker, microservices, CI/CD, and event-driven systems.
