Backend, APIs and integrations
What a user sees depends on what happens behind the interface. We design APIs, databases and integrations so applications can share information with clear rules, appropriate access and errors that can be investigated.

A client portal, a team app and a scheduling tool may need the same information in different forms. Contracts, authentication and state transitions are defined before systems are connected. We work with the existing environment and plan migrations and deployment around preserving business data.
What we work on
- Endpoint design, data contracts and the data model.
- Authentication, authorisation and role separation.
- External integrations and failure handling.
- Tests for business rules and critical workflows.
- Migrations, operational records and handover documentation.
How we work together
Our portal provides proposals, payments, documents and conversations according to each person's role. The clinic platform connects booking and reception. These examples help make data ownership, permissions and failure behaviour concrete.
Before we start
Can you integrate a third-party service?
We first check its APIs, permissions, limits and technical conditions. That review defines the workflow and how changes, failures or repeated responses will be handled.
How are updates planned around existing data?
Through environment review, controlled migrations, checked backups and a defined recovery strategy. The procedure is prepared for the specific system and verified within that scope.
