Custom OpenAS2 Server Setup on Ubuntu

I am looking for an experienced freelancer to integrate the MediaMarktSaturn (MMS) EDI interface using the AS2 protocol. The project involves setting up the infrastructure and configuring the data exchange for key EDI messages such as **Order**, **Order Response**, **DESADV (Dispatch Advice)**, and **Invoice**.

Key Requirements:

* Configure an OpenAS2 server on a Linux system (preferably Ubuntu) for secure AS2 communication with MediaMarktSaturn's EDI system.
* Implement the EDI data exchange for the following message types:

* Order (ORDERS)
* Order Response (ORDRSP)
* DESADV (Dispatch Advice)
* Invoice (INVOIC)
* Ensure secure data transmission by properly setting up encryption, digital signatures, and authentication protocols as per AS2 standards.
* Customize the AS2 configuration to meet the specific integration requirements of MediaMarktSaturn.
* Provide documentation for the setup and guidance for ongoing maintenance and troubleshooting.
* Set up the necessary MDN (Message Disposition Notification) handling for both sending and receiving responses.

Ideal Skills and Experience:

* Strong experience with OpenAS2, including installation, configuration, and customization.
* Familiarity with AS2 protocol and secure data transmission standards (encryption, digital signatures, MDN handling).
* Knowledge of EDI standards, especially for Order, Order Response, DESADV, and Invoice messages.
* Proficiency in Linux (preferably Ubuntu), including server administration, installation of dependencies, and configuration.
* Ability to troubleshoot EDI communication issues and ensure seamless data exchange.
* Experience with MediaMarktSaturn (MMS) EDI integration is a plus.

If you have the expertise in configuring OpenAS2 servers, EDI integration, and working with AS2, please get in touch. I am looking forward to your application!
