New Doorway to Old Systems

A REST doorway in front of the systems you cannot retire, so anything new you build stops inheriting their limits.

Connected Systems & Payments Read the details
Overview

Some core systems are not going anywhere for years. Banking platforms, insurance systems and government interfaces still run on SOAP, on fixed-width files, on formats older than the people looking after them. A doorway in front translates the protocol, renames cryptic fields into words a person can read, and adds caching and circuit breakers so a sluggish back end cannot drag your website down. New work builds against a clean, documented interface, and when that old system is finally switched off, only this layer changes.
