What exactly did you implement in this microservice?

In this microservice, I implemented business logic for data processing, including:

• Developing REST API for client interaction.
• Handling incoming requests with validation and data transformation.
• Integrating with a database for storing and retrieving information.
• Error handling and logging for monitoring.

For example, I implemented an endpoint for creating an entity, where data was validated for correctness, then saved to the database, and the operation result was returned to the client.
