API Design & Integration for Defence & Aerospace

Idempotency keys on every write endpoint prevent the duplicate-charge class of bug entirely. It is a small amount of work that removes an entire category of incident.

In defence & aerospace, systems must run fully air-gapped, on open weights, with no external dependency whatsoever. That single fact reshapes how api design & integration has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is maintenance prediction, usually integrated against simulation platforms. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.

Built by engineers who ship production systems, not by a practice that subcontracts the build. We hand over with runbooks, tests and a team that knows how it works, not a dependency.
