Builds flexible API filtering and sorting systems with query parameter parsing, validation, and security. Use when implementing search endpoints, building data grids, or creating dynamic query APIs.
Build production-grade FastAPI backends with SQLModel, Dapr integration, and JWT authentication. Use when building REST APIs with Neon PostgreSQL, implementing event-driven microservices with Dapr pub/sub, scheduling jobs, or creating CRUD endpoints with JWT/JWKS verification. NOT when building simple scripts or non-microservice architectures.
ASP.NET Core Web API implementation: clean controllers with CQRS, global error handling, model validation, Swagger/OpenAPI, API versioning, security (CORS, auth), middleware pipeline, and performance patterns. Use when creating or editing controllers, filters, middleware, Program.cs, or API endpoints.
REST and GraphQL API testing with Playwright. Use when testing APIs, mocking endpoints, validating responses, or integrating API tests with E2E flows.
Expert API designer for REST, GraphQL, gRPC architectures. Activate on: API design, REST API, GraphQL schema, gRPC service, OpenAPI, Swagger, API versioning, endpoint design, rate limiting, OAuth flow. NOT for: database schema (use data-pipeline-engineer), frontend consumption (use web-design-expert), deployment (use devops-automator).
Browse and search Reddit in read-only mode using public JSON endpoints. Use when the user asks to browse subreddits, search for posts by topic, inspect comment threads, or build a shortlist of links to review and reply to manually.
