What was the project in the company? What microservice was there?

The company had a project to develop a high-load service for processing user requests in real-time. My task was to create a microservice responsible for user authentication and authorization.

This microservice implemented OAuth 2.0 and JWT for secure session management. It interacted with other services via gRPC and REST API, ensuring system scalability and fault tolerance.

Examples of key functions of the microservice:

• Credential verification
• Token issuance and renewal
• Login attempt logging

This approach helped offload the main application and increased security.
