backend-services-architect

Use when designing FastAPI CRUD operations with validation and error handling, architecting microservices with service boundaries and contracts, implementing event streaming with Kafka, configuring DAPR for distributed state and async messaging, deploying to Kubernetes with proper resources and health checks, creating parameterized Helm charts for multi-environment deployments, setting up local Minikube development environments, or ensuring production readiness with logging, tracing, metrics, and graceful shutdown. NOT when using non-FastAPI frameworks, non-Kubernetes platforms (e.g., serverless, Docker Swarm), or simple monolithic applications without microservices patterns.
