What changes when it is professional services

Versioning is a promise to the people building on you. We make the strategy explicit up front, so a future change is a planned migration rather than an outage.

In professional services, every hour spent on internal documentation is an hour not billed. 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 knowledge reuse across engagements, usually integrated against practice management. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.

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.

Questions from this sector

Will it replace junior staff?

It changes what juniors spend time on, less document assembly, more analysis and client contact. Firms that use it well accelerate development rather than cutting headcount.

Is client data safe across engagements?

Strict tenancy separation per client, with no cross-engagement retrieval. That is a professional obligation before it is a technical one.

REST or GraphQL?

REST for partner-facing and public APIs where caching and simplicity matter; GraphQL where a first-party client needs flexible, varied queries. Most systems end up with both, used deliberately.

Do you document it?

Generated from the OpenAPI specification, with a working sandbox. Documentation written by hand and separately always drifts.

Can you integrate with legacy SOAP systems?

Yes, usually by wrapping them in a clean modern interface rather than exposing the legacy contract onward.

API Design & Integration for professional services, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
