To design a RESTful API with JWT authentication, define resource endpoints for user management and implement secure token-based authorization. This skill provides the architectural framework to structure endpoints, integrate databases, and enforce authentication mechanisms for scalable server-side applications.

Integrating PostgreSQL and MongoDB in a microservices architecture involves assigning specific database technologies to individual services based on their data requirements. This approach supports distributed systems by enabling polyglot persistence and maintaining scalable, maintainable data layers.

Yes, you can implement both gRPC and GraphQL APIs. This backend development capability covers multiple API paradigms, allowing you to choose RESTful endpoints, GraphQL schemas, or gRPC protocols depending on your specific inter-service communication and client data-fetching requirements.

Microservices architecture handles secure authentication and authorization across distributed systems by implementing centralized identity verification and decentralized access control. This ensures secure data handling and efficient database interactions across independent services without compromising scalability.

You should avoid microservices architecture when your application scale does not justify the operational overhead of distributed systems. For smaller applications, a monolithic backend development approach maintains simpler database integration and security implementation without complex inter-service communication.
