Define service boundaries, design domain-driven microservices, and create API contracts. Reasoning models evaluate coupling, cohesion, and data ownership.
Generate Dockerfiles, Kubernetes manifests, Helm charts, and docker-compose configs. Models understand resource limits, health checks, and scaling policies.
Design Kafka topics, RabbitMQ exchanges, and event schemas. JSON mode produces structured event contracts compatible with schema registries.
Implement gRPC services, REST APIs, and GraphQL federation. Function calling models understand service-to-service authentication and circuit breakers.
