Overview

What this service delivers

The server you write today decides how painful every later change will be. We build an API meant to be extended: tidy resource handlers, validation on every incoming request, database migrations that run from an empty database without errors, and queued jobs for anything slow. Tests cover the parts where a mistake would hurt. Every endpoint is written up in a standard machine-readable specification, on the relational database you prefer, so front-end and app developers can see exactly what each call expects and returns.

    We agree the data model and the business rules with your domain expert

  2. Step 2: Contract

    The API specification is written first, so client work can begin early

  4. Step 4: Release

    Deployment to your chosen hosting, followed by a handover session
