Tell about the last task or project you participated in and your contribution to it.

In my last project, I worked on developing a web application for team task management. My main role was implementing backend logic in Java using Spring Boot.

My contributions included:

• Designing REST API for creating, updating, and deleting tasks.
• Implementing user authentication and authorization systems.
• Optimizing database interactions through JPA and writing complex queries.
• Writing unit tests to ensure code quality.

Thanks to my work, the application's performance was improved, and the user experience was enhanced through quick response times and reliable service operation.
