About the project

The organization is a client of Proxiad for about 2,5 Years.

The goal is to migrate the components of the legacy frameworks which are written in C and java to a framework written in a newer java framework. Among these components are batches, different use cases within the framework and stand-alone applications.  They span from various departments and activities of the bank and are responsible for its core business. A further goal is to migrate the existing technology landscape (jboss, spring, hibernate, external libraries) to the newest versions.


Our client achieved excellent cost-benefit effect. Furthermore we enabled an update of the technology stack assuring that its services continue to be on a top level.
