Systems integration
Legacy Integration Layer
A modern REST API that fronts a decades-old mainframe operating system with no API of its own — turning manual terminal data-entry into a programmatic call that completes in under a second.

What you'll be able to do
- ▹Fill in a container move — from-slot to to-slot — and submit it.
- ▹Watch the request travel through a simulated mainframe message-queue round-trip.
- ▹Inspect the fixed-format message envelope, byte by byte.
How the real system works
- ▹A modern REST API fronts a legacy mainframe that exposes no API of its own, communicating over its internal message-queue interface.
- ▹This demo simulates that round-trip end to end — the real system completes an actual move in under a second.
This demo is an independent, clean-room rebuild of a system I designed in a professional setting. It contains no proprietary code, data or system internals — everything shown runs on fictional terminal data.
