Functional Application Manager at Vattenfall improving SAP IS-U and EDM metering-data processes with Power BI dashboards.

Netherlands
Message

At Vattenfall, I manage and optimize applications supporting metering-data and energy processes, including SAP IS-U and EDM. I analyze incidents and data-flow issues, monitor data quality, and translate business requirements into functional solutions.

I create Power BI dashboards and reports to monitor data flows, exceptions, and operational performance. I also document processes and support changes, releases, and testing with business users, IT teams, suppliers, and operational stakeholders.

Earlier, I managed business-critical applications across banking and media, including SAP BCM telephony and SAP ERMS email systems at Sanoma Media Nederland B.V. I’ve also worked in customer service, testing, application support, and photography.
