Tell about the tasks you solved in your previous projects.

In previous projects, I tackled the following tasks:

• Development of REST APIs for web applications using Spring Boot, including CRUD operations and authentication.
• Performance optimization of applications through code refactoring and caching implementation.
• Integration with external services via HTTP and SOAP, error handling, and logging.
• Writing unit and integration tests using JUnit and Mockito.
• Working with databases (MySQL, PostgreSQL), writing complex SQL queries, and index optimization.

For example, in one project, I implemented an order management system, where I was responsible for backend logic and database interaction.
