Event-Driven Architecture That Stays Correct Under Failure

That service automates workflows and connects systems broadly. This is the dedicated event-driven architecture engagement — queue/pub-sub topology and the delivery-guarantee, idempotency and dead-letter design that make async correct at scale.

Not always. For simple request/response, synchronous is simpler and we will say so. Async earns its complexity with spiky load, long-running work, fan-out, or third-party webhooks — we assess fit first.

Idempotent consumers keyed on event identity, so reprocessing the same event has no harmful effect. This is designed in, not patched on after a double-charge incident.

Bounded retries with backoff handle transient failures; persistently failing messages go to a dead-letter queue with alerting, so one poison message cannot silently stall the pipeline.

Managed queues/streaming and pub/sub appropriate to your stack and scale. We choose by workload and operational fit rather than defaulting to one broker.

Yes — we commonly introduce an event layer incrementally alongside existing synchronous APIs, with our database & API team, rather than requiring a rebuild.
