API + Integration work at IRPR.io is the plumbing between systems — the thankless layer that makes every product feel seamless. Third-party SaaS integrations, internal-service API contracts, webhook handlers, event buses, and the reliability engineering that keeps it all flowing under real load.
Production-grade, by default.

API & Integration · how we actually work.
We've integrated every major CRM, billing platform, commerce system, marketing tool, support tool, and payment processor. The integrations that are 'just glue code' on the surface are where most production outages actually live — and we engineer them accordingly.
Every integration we ship has retry logic, observability, idempotency keys, dead-letter queues, and documented recovery procedures. Not because it's fancy — because it's what production looks like at 2am.

What production integration work actually looks like.
The parts that get silently skipped — and then cause Saturday-night incidents.
Integration code that holds up vs. the kind that doesn't.
- fetch + JSON.parse
- no retry/backoff
- silent on failure
- no observability
- schema drift breaks silently
- Saturday 2am incidents
- typed client + retry library
- exponential backoff + jitter
- dead-letter queue + replay
- Datadog dashboard + alerts
- typed schema contracts
- on-call doesn't call us
