Can you tell about your recently implemented project and your participation in it?

In one of my recent projects, I developed a web application in Java using Spring Boot. My task was to implement a REST API for managing users and their roles. I designed the database structure, created JPA entities, wrote the service layer and controllers. I also integrated with an external authentication service via OAuth2. For testing, I used JUnit and Mockito. As a result, I created a scalable and easily maintainable application that is successfully used in production.
