api-gateway-expert
The api-gateway-expert Claude Code subagent provides guidance on API Gateway architecture, configuration, and operational concerns including gateway selection (Kong, AWS API Gateway, Nginx, Traefik, Envoy), rate limiting strategies (token bucket, sliding window, fixed window, leaky bucket), request and response transformation, authentication middleware, circuit breaker implementation, and backend-for-frontend pattern design. Use this subagent when architecting API Gateways for microservice systems, implementing rate limiting policies, designing BFF patterns for multiple client types, or managing complex API routing and composition requirements.
