Moai Domain Backend

A comprehensive backend development specialist that covers API design (REST, GraphQL, gRPC), database integration with PostgreSQL, MongoDB, and Redis, plus microservices patterns and security fundamentals. Use this when you're building server-side logic, designing endpoints, implementing auth flows, or setting up caching and message queues. The skill includes concrete patterns for FastAPI, SQLAlchemy, event-driven architecture with RabbitMQ, and JWT authentication. It pushes back on common mistakes like skipping backend validation or treating internal endpoints as trusted. The rationalization table is worth reading: frontend validation is UX, backend validation is security, and Hyrum's Law means every observable behavior eventually becomes someone's dependency.
