Versioned contracts, recoverable flows

API integration services for CRM, ERP and B2B systems.

I design and build API integrations with explicit contracts, idempotent processing, bounded retries, structured logging and reconciliation so cross-system records can be checked, repaired and traced.

Integration lifecycle

Contract design -> validation -> idempotent processing -> retries with backoff -> dead-letter visibility -> reconciliation -> versioned change management.

Contract-first design

Versioned API and event schemas with explicit compatibility rules for changes that affect consumers.

Reliability controls

Idempotency keys, unique constraints, bounded retries and replayable dead-letter queues are selected for the agreed failure modes.

Reconciliation evidence

Correlation IDs, structured logs and scheduled reconciliation help operators verify whether records match.

Not sure where you stand?

Start with the free tools: score your current integration or compare build-vs-buy costs before committing to a project.

Production-readiness artifacts

A production-ready integration ships with a field ownership matrix, example payloads, an error catalog, monitoring views and a documented rollback path.

Check your integration before you commit to a build — no registration required.
