Tell me about the last or most interesting project you participated in, preferably related to microservices. What was it architecturally and technically, and what role did you play in it?

In one of my recent projects, I participated in developing a distributed system based on microservices architecture for processing orders in e-commerce. The system architecture consisted of several services: order management service, payment service, notification service, and analytics service. All of them interacted through asynchronous message queues (RabbitMQ), which ensured loose coupling and scalability.

My role was to develop the order management service using Python with FastAPI. I was responsible for implementing business logic, integrating with a PostgreSQL database, and configuring interactions with other services via messages. I also handled writing unit and integration tests, as well as setting up CI/CD pipelines for automatic deployment.

This approach allowed us to quickly scale the system and easily add new features without affecting other services.
