Can you tell about your main responsibilities and tasks in your last project?

In my last Java project, I was involved in developing the server-side of a web application. My main responsibilities included:

• Designing and implementing REST API using Spring Boot.
• Working with the database through JPA/Hibernate: creating entities, writing queries.
• Writing unit and integration tests to ensure code quality.
• Optimizing performance and fixing bugs.
• Collaborating with the team through version control system Git and participating in code reviews.

For example, I implemented user registration functionality with data validation and database storage.
