Message

At Volkswagen AG, I support the annual financial close and develop reports and analyses for the financial steering of aggregate development. I also redesigned the data model and developed new ETL pipelines to modernize an existing data warehouse landscape.

Previously, I managed data warehouse applications at Volkswagen AG and developed BI solutions at Volkswagen R GmbH and Saracus Consulting GmbH. My work included data-quality and governance standards, ETL development, reporting, and support for finance and sales controlling.
