We design and build the interfaces your systems and partners depend on: contract-first, versioned, documented, and engineered for the failure cases that actually occur.
Contract first, always
The specification is written and agreed before implementation, so consumers build in parallel and nobody discovers a mismatch during integration testing.
Designed for failure
Idempotency keys, exponential backoff, circuit breakers, dead-letter queues and replay. Distributed systems fail constantly; the difference is whether that failure is visible and recoverable.
Events where coupling hurts
Request/response is right for queries. For state changes with many interested parties, an event backbone removes the coupling that makes every change risky.
