Generate gRPC services with Protocol Buffers and streaming support
gRPC testing: buf lint and breaking-change gates, ghz load tests, grpcurl, mock servers, and streaming RPC test suites. Includes the protobuf versioning catalog, interceptor test patterns, and a status-code catalog. A review agent (grpc-service-reviewer) flags missing status-code assertions and deadline handling. Distinct from qa-contract-testing/protobuf-compat-checking (schema-level breaking detection).
integrations-protocols
Design and implement backend services and APIs — REST, gRPC, GraphQL, event-driven handlers, transaction boundaries, outbox/inbox delivery, migration coexistence, database access, integration, error handling, and service-level testing. Use for application/domain/infrastructure implementation decisions. Language and framework agnostic. Do not use for frontend, data engineering, platform provisioning, API contract ownership, service decomposition strategy, or cross-system migration planning.
Real-time protocol testing: WebSocket handshakes and close codes, Server-Sent Events, and MQTT v5 QoS, retained messages and shared subscriptions. Includes SSE load testing with k6 and STOMP / AMQP broker testing in references. A review agent (realtime-protocol-reviewer) flags missing reconnect backoff and unhandled close codes. gRPC streaming lives in qa-grpc and webhooks in qa-notifications.
integrations-protocols
OpenTelemetry in Go: declarative SDK setup with otelconf, API surface, contrib instrumentation libraries (otelhttp, otelgrpc), compile-time zero-code instrumentation (otelc), performance tuning, breaking-change audits.
Backend, API & distributed-systems QA role bundle: one-command install of API/contract/GraphQL/gRPC/real-time testing, auth flows, notifications, payment, async jobs, DB migrations, caching, concurrency, saga/CQRS, distributed tracing, serverless, time/timezones, and feature flags + experimentation.
