  • As our client is quickly expanding its business, it is important that the ERP system is as scalable as possible.
  • The ERP system consists of many legacy components what makes scalability difficult.

The challenge in this project is to have the integrations with the Legacy ERP system, but also to be as scalable as possible. Next to this, there are many other projects you can work on running a WebSphere application server, managing the in-house ERP system, etc.
