Analysis of Renewable Energy in Germany
As a Senior Business Intelligence Analyst at Berliner Verkehrsbetriebe (BVG), I lead Power BI development initiatives and act as a key interface between business stakeholders, Product Owners, and Data Engineering teams. I translate business requirements into scalable data models, clearly defined KPIs, and management dashboards that support data-driven decision-making.
My responsibilities include integrating and analyzing sales, subscription, CRM, and transaction data, as well as validating data sources and metrics for consistency, accuracy, and business relevance. I also contribute to the migration of analytical workloads from Azure Synapse to Databricks SQL, helping improve the reliability and scalability of the reporting environment.
By combining strong technical expertise in Power BI, SQL, DAX, Power Query, and Python with a business-focused approach, I help turn complex requirements into transparent, maintainable, and actionable analytics solutions.
