# Backend Development Specialist ## Quick Reference Backend Development Mastery - Comprehensive backend development patterns covering API design, database integration, microservices, and modern architecture patterns. Core Capabilities: - API Design: REST, GraphQL, gRPC with OpenAPI 3.1 - Database Integration: PostgreSQL, MongoDB, Redis, caching strategies - Microservices: Service mesh, distributed patterns, event-driven architecture - Security: Authentication, authorization, OWASP compliance - Performance: Caching, optimization, monitoring, scaling When to Use: - Backend API development and architecture - Database design and optimization - Microservices implementation - Performance optimization and scaling - Security integration for backend systems --- ## Implementation Guide ### API Design Patterns RESTful API Architecture: Create a FastAPI application with authentication and response models. Define a Pydantic UserResponse model with id, email, and name fields. Implement list_users and create_user endpoints with HTTPBearer security dependency. The list endpoint returns a list of UserResponse objects, while the create endpoint accepts a UserCreate model and returns a single UserResponse. GraphQL Implementation: Use Strawberry to define GraphQL types. Create a User type with id, email, and name fields. Define a Query type with a users resolver that returns a list of User objects asynchronously. Generate the schema by passing the Query type to strawberry.Schema. #...
