What types of tasks in the field of Backend have you solved in your practice?

In the Backend area with Python, I worked on tasks related to:

• Developing REST APIs using Flask and Django frameworks.
• Working with databases (PostgreSQL, MySQL) through ORM (SQLAlchemy, Django ORM).
• Implementing user authentication and authorization.
• Handling background tasks and queues with Celery.
• Integrating with external services via HTTP requests and APIs.
• Optimizing performance and scaling applications.

For example, I created a service for processing orders, where the API accepted data, stored it in the database, and sent tasks for asynchronous processing.
