About Mareike

I help companies transform their financial and business data into clear, decision-relevant information. My focus is on controlling, reporting, and data-driven analysis using Power BI, Excel, and SAP – turning complex numbers into understandable KPIs and recommendations for action.

With my experience in maintenance control at DB and in production and project controlling at Infineon, I am very familiar with the requirements of large, data-driven organizations. I work in a structured and reliable manner, with a strong understanding of processes, data quality, and business contexts.

What particularly distinguishes me is my combination of operational controlling experience and technical implementation expertise in reporting tools. Typical projects I undertake include KPI dashboards in Power BI, Excel-based reporting and forecast models, data preparation in SAP, and the optimization of existing reporting and controlling processes.
