What microservices have you developed?

In my Go projects, I developed microservices for various tasks, such as:

• Authentication and authorization service for users with JWT and OAuth2.
• Payment processing service that interacts with external bank APIs.
• Product catalog management service with REST API and support for filtering and pagination.
• Notification sending service (email, push) that processes message queues.

Each microservice was isolated, had its own database, and interacted with others via HTTP/gRPC. This allowed system scalability and simplified maintenance.
