This is what you reach for when you're architecting a new backend service and need to think through service boundaries, API contracts, and how everything fits together before writing code. It covers the full spectrum: REST, GraphQL, gRPC design, event-driven patterns with Kafka and message queues, microservices communication, and observability setup. The real value is in the structured approach to capturing requirements, defining contracts, choosing patterns, and planning resilience upfront rather than bolting it on later. Best for greenfield services or major refactors where you need architectural thinking, not for tweaking existing endpoints or debugging.
