Queue-Based Async Processing

Moved heavy and third-party work off the request path into queued workers — keeping the app fast and resilient to slow external APIs.

Context: emails, exports, LLM calls and integrations were blocking requests. Decision: push them to background workers (Laravel Queues / Redis+ARQ) with retries, backoff and rate limits. Trade-off: eventual consistency for those tasks in exchange for a fast, reliable UI and graceful handling of external failures.

Laravel QueuesRedis + ARQSupervisor

What it does

  • Request path stays fast; slow work runs in workers with retries & backoff.
  • Rate limiting & idempotency to survive flaky third-party APIs.
  • Supervisor / ARQ-managed workers with monitoring.
