Describe the main functions and responsibilities you implemented in your previous project.

In my previous project, I implemented the following main functions:

• Development of REST API for database interaction using Flask/Django.
• Processing and validation of incoming user data.
• Implementation of business logic, such as user management, order processing, or analytics.
• Integration with external services via API.
• Writing unit tests to ensure code quality.
• Performance optimization and bug fixing.

For example, I created endpoints for user registration and authentication, where I implemented data validation, database storage, and access token generation.
