Before we write a line of integration code, we verify your checklist: domain events are named by business facts, consumers declare schemas, and failure paths are replayable without silent drops.

Project models for event-driven work

Engagements are fixed-scope programming projects—not open-ended staff augmentation. Each quote lists deliverables tied to brokers, handlers, or outbox tables you already run.

Broker readiness review

We audit topic partitioning, retention, and consumer lag alarms for Kafka, RabbitMQ, or cloud-native buses you operate in Taiwan or hybrid regions.

Outbox & idempotency spike

Time-boxed implementation of transactional outbox or inbox patterns against your existing RDBMS, with chaos tests on duplicate delivery.

Contract hardening sprint

Schema registry rules, compatibility gates, and CI checks so event payloads cannot break downstream services without an explicit version bump.

Checklist: signals your architecture is event-ready

Producers emit past-tense domain facts, not imperative commands disguised as events.
Consumers tolerate at-least-once delivery with deterministic idempotency keys.
Operational dashboards show consumer lag, poison-queue depth, and replay tooling owners trust.
Cross-team contracts are versioned; breaking changes require a published migration window.

Questions teams ask before an event-driven rewrite

Do you replace our message broker?

Usually no. We integrate with the broker and observability stack you already pay for, then document topology changes only when throughput or ordering requirements demand it.

Can you work alongside our Taipei engineering group?

Yes. Workshops run in English with async follow-ups; pairing sessions target handlers, serializers, and deployment manifests in your repository.

What do you deliver at the end of a project?

Runnable code, replay runbooks, contract tests, and a written decision log explaining trade-offs on ordering, sagas, and dead-letter handling.

Send a scoped inquiry

Describe brokers, languages, and the business workflow you want to decouple. We reply by email with clarifying questions—no automated scheduling links.
