What microservices did the backend consist of? Can you recall what services they were?

The backend consisted of several microservices, each responsible for a specific business logic:

• User Service — user management, authentication, registration.
• Order Service — order processing, creation, status updates.
• Product Service — product catalog, product information.
• Payment Service — integration with payment systems, transaction processing.
• Notification Service — sending notifications to users (email, push).

Each service had its own database and API, and interaction between them occurred via REST or message queues (e.g., RabbitMQ). This architecture allowed for scaling and developing parts of the system independently.
