A modern interface. A COBOL calculation.
Follow a synthetic order from a typed web form through a fixed-width record contract to a native business-processing program.
IVAN FERLAND / Enterprise & multi-location organizations
A defined workstream. An accountable specialist.
For technical leads and operational sponsors with a specific application, integration or modernization problem. I work alongside your developers, IT team, MSP and vendors, with a clear delivery boundary and someone on your side who owns acceptance.
← HomeWhat needs to work better
- A legacy interface stands between a useful business rule and a modern application.
- Different locations follow the same process with inconsistent records, dependencies or exception handling.
- A technically small change crosses identity, data, deployment and operational ownership boundaries.
Concrete deliverables
- Discovery covering interfaces, data ownership, dependencies and the acceptance criteria for a defined workstream.
- A tested internal tool or integration with explicit validation, error handling and operational visibility.
- Environment configuration, release and rollback instructions, documentation and handover to the responsible team.
POSSIBLE ENGAGEMENT
A modern interface around established logic
A possible engagement: document an existing record contract, build an adapter and prove that agreed business rules survive the new interface. Legacy Bridge demonstrates this pattern with an actual compiled GnuCOBOL executable and inspectable request/result transformations.
- 01
Agree the contract, permissions and representative test records.
- 02
Prove compatibility in a separate test environment.
- 03
Validate normal, boundary and failure behavior before an agreed release.
An approach that fits your team
Identity and access, environment separation, observability, deployment approval and recovery are project requirements to settle with your team. Review points expose working results and unresolved dependencies. National implementation and database-modernization cases provide relevant operational context.
I offer an independent contribution to a defined workstream, not a replacement for an enterprise operations team. The GnuCOBOL example does not establish IBM mainframe deployment or qualification.
