MAI THANH TÙNG

I’m a Java Backend Developer with hands-on experience building backend applications using Java, Spring Boot, Spring Security, JPA/Hibernate, MySQL, PostgreSQL, and Redis. Through internship experience and real-world projects, I have developed RESTful APIs, implemented authentication and role-based authorization, caching, and handled backend business logic following structured application architectures.

I have also worked with JWT, OAuth2, TOTP/2FA, OpenAI API integration, payment services, and webhooks, giving me practical experience integrating backend systems with external services and handling real application workflows.

Beyond application development, I’m familiar with Docker, Maven, Git, GitHub, GitHub Actions, and CI/CD pipelines, allowing me to build, package, and deploy applications in a more consistent and maintainable way.

My strengths are understanding backend logic and data flow, debugging problems systematically, and writing clean, maintainable code. I value teamwork, clear communication, and continuously improving both my technical knowledge and software engineering practices.

In the next 1–2 years, I aim to grow into a well-rounded Backend Developer who can confidently design and develop scalable, secure, and production-ready backend systems while taking greater ownership of system architecture and technical decisions.
