Can you work within data-residency rules?

Yes. Where data may be stored and processed is decided before the schema, and the infrastructure is defined as code so the boundary can be shown to an auditor.

Can AI be used on sensitive records?

Sometimes. It depends on the data, the provider's terms and your policy. We tell you which provider would receive what, and design so a person reviews anything consequential.

How do you release into a short change window?

By rehearsing the cutover on a copy of production, timing it, and testing the rollback as carefully as the release.

Industries Health & Public

Systems inside real constraints: procurement, legacy data, and a four-hour change window.

In short

Health and public-sector systems cannot stop for a rewrite. The old system stays live, the data stays where the law says, and a release window may come a few times a year. We modernise in place, with the migration rehearsed and the rollback tested.

Health & Public: Systems inside real constraints: procurement, legacy data, and a four-hour change window.

What we see

The problems this sector brings

Legacy interfaces nobody owns and nobody may switch off
Data that cannot leave a jurisdiction or a boundary
Release windows measured in hours, a few times a year

How we work

What we do about them

Strangler-pattern migration with the legacy path live throughout
Data residency and access boundaries designed before the schema
Rehearsed cutovers with a tested rollback, not a hopeful one

What we build

Systems we build for health & public

01
Legacy modernization
Strangler-pattern migrations that move one function at a time while the old system keeps running.
02
Records and case systems
Web applications over sensitive records, with access controls and an audit trail for every view and change.
03
Document processing
Extraction from forms, scans and letters, with a person reviewing anything the system is unsure of.
04
Integration layers
APIs in front of older systems, so new services can be built without touching the core.
