Could you tell about your role and tasks in the latest project implementation?

In my last project, I served as a Java developer, responsible for developing and maintaining server-side logic. My tasks included writing REST APIs, integrating with databases using JPA/Hibernate, and writing unit tests with JUnit. Additionally, I participated in code reviews and performance optimization of the application. For example, I implemented a service for processing user requests that ensured high response speed and correct transaction handling.
