Quick Answer
Async patterns at scale: event-driven architecture (EventEmitter/MessageBus between modules), worker pools for CPU tasks, request queuing to rate-limit API calls, optimistic UI updates with rollback, Saga pattern for multi-step async flows, and circuit breakers for external service calls. Avoid long sequential await chains for operations that could run in parallel.
