API Design & Integration for Construction & Infrastructure

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 construction & infrastructure, sites are dispersed, connectivity is poor, and documentation lags reality by weeks. 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 subcontractor invoice validation, usually integrated against document control systems. Every engagement opens with a measurement: the cycle time, the cost per transaction, or the error rate we are being asked to move.

Deployed across regulated and unregulated sectors, with audit trails where the regulator expects them. We hand over with runbooks, tests and a team that knows how it works, not a dependency.
