APIs that are easy to use, safe to open, and hard to break
Most integration problems are not about technology. They come from point-to-point connections nobody documented, services split too early, and one slow system dragging others down with it. We help you design APIs and services that stay understandable as they grow.
Why integration gets painful
Spaghetti connections
Every system talks directly to every other. Change one, and you find out what breaks in production.
Microservices too early
A small team split one application into twenty services and got all of the complexity with none of the benefit.
Nobody knows which APIs exist
Old versions and test endpoints stay open on the internet, with no owner and no monitoring.
One slow service stops everything
A service waits forever on a slow dependency, threads pile up, and the failure spreads.
Gateway checks, rate limits and a circuit breaker
Send requests as a valid partner and as an unknown caller. Send a burst to hit the rate limit. Then switch the payments service to failing, and watch the circuit breaker stop the orders service from waiting on it.

How an integration engagement runs
- Map what talks to what. Every integration, its owner and what breaks if it stops.
- Decide the shape. Which domains need clear APIs, where events fit, and what should stay as it is.
- Put a gateway and catalogue in front. One place for keys, limits, documentation and monitoring.
- Change gradually. Replace the worst point-to-point links first, without a big-bang rewrite.
- Make failure safe. Timeouts, retries and circuit breakers on every call between services.
- Hand over. API guidelines, templates and review practice your teams can follow.
