Systems Integration
API & Middleware Development
Building the layer between two systems that don't speak the same language — translating formats, handling authentication, retrying failures — so each side can be built, tested, and changed independently.

What it is
When two systems need to talk to each other but weren't built together, something has to sit between them — translating data formats, managing authentication, and handling the failures that come with any network call. That middleware layer is what lets each side keep evolving independently instead of being tightly coupled to the other's internals.
How it works
- 01Define the contract
What data crosses the boundary, in what format, and what each side can expect from the other — an explicit interface, not an implicit assumption.
- 02Handle auth and failure modes
Authentication, retries, timeouts, and rate limits built in from the start — the parts that don't show up in a demo but break production.
- 03Keep each side independently testable
The middleware is built so either system can be updated or replaced without forcing a change on the other.
- 04Document the interface
A written contract for the API or middleware, so a future integration doesn't have to reverse-engineer it from the code.
Benefits
- Two systems that can evolve independently instead of being tightly coupled
- Auth, retries, and failure handling built in, not discovered in production
- A documented interface for whoever integrates against it next
Frequently asked
Do you build public APIs or only internal middleware?
Both — the approach is the same either way: a defined contract, proper auth, and documented failure behavior, whether it's consumed internally or by external partners.
What if one of the systems changes its API later?
That's exactly what the middleware layer is for — absorbing that change on one side without forcing a rewrite on the other.
