Legacy Integration for a Transmission System Operator

For a German transmission system operator, I developed a cloud-native adapter between legacy software and the publication platform of the association of transmission system operators (ENTSO-E). The adapter automates the publication of Outage Planning Coordination (OPC) information that was previously transferred manually.

For this purpose, I:

• Developed cloud-native data integration software based on Spring Boot,
• Bridged the legacy system’s SFTP/MFT file transfer to an event-driven pipeline using a claim-check pattern,
• Transformed multiple XML documents into a standardized ENTSO-E format for publication,
• Implemented an Angular web app for tracking published notifications,
• And connected error notifications to MS Teams via webhook.
