}I am an IT student at the University of Information Technology, VNU-HCM (UIT), with backend development as my main direction. Java, Spring Boot, and PostgreSQL are the stack I use most while building MonoMarket.
I am interested in what happens below an endpoint: relational database state, transactions, consistency, tests, containers, and deployment. When a feature fails, I usually trace the logs and database state before changing the design.
I am also studying Japanese for future software engineering opportunities in Japan.

MonoMarket is a server-rendered second-hand e-commerce platform inspired by Japanese reuse stores. It uses Spring Boot, Spring MVC, Thymeleaf, PostgreSQL, Hibernate/JPA, Spring Security, Flyway, Maven, Docker Compose, GitHub Actions, MockMvc, Mockito, H2, and Swagger/OpenAPI.
| Engineering area | Implementation focus |
|---|---|
| Cart state | Guest carts merge into the authenticated user's cart after login. |
| Inventory and orders | Serialized inventory represents unique stock; checkout and cancellation keep reservation state consistent. |
| Database | PostgreSQL schema changes are versioned with Flyway migrations and modeled through relational entities. |
| Testing | Spring Boot tests use MockMvc, Mockito, and H2 to exercise web and application behavior. |
| Local delivery | Docker and Docker Compose run the application with PostgreSQL; GitHub Actions runs Maven verification. |
| Web architecture | Spring MVC and Thymeleaf keep the customer flow server-rendered. |
| IDE / Editor | Database | API testing | Containers | AI-assisted development | Version control |
|---|---|---|---|---|---|
| IntelliJ IDEA · VS Code | DBeaver | Postman | Docker | Codex | Git |
