What we can deliver

  • Inspect the existing interface, record formats and constraints.
  • Define an explicit contract between the old and new components.
  • Implement adapters, validation and controlled failure behaviour.

DEMO CAPTURE

What you receive

  • A documented data contract and a small compatibility proof.
  • A tested integration with representative success and failure cases.
  • Deployment, rollback and troubleshooting notes.

To get started

  • System documentation and representative synthetic or anonymized records.
  • Known business rules, rounding requirements and data ownership.
  • A safe test environment and an agreed deployment boundary.

Start with a description; we can work through the details together.

Technical boundaries and scope
  • No arbitrary production database changes or uncontrolled execution.
  • Compatibility must be proved in the actual target environment.
  • Historical behaviour that cannot be verified stays an open question until resolved.
