Hi, I’m

Summary

I turn messy data into decisions that actually move the needle.

With a background in business analysis, sales operations, and process improvement, I have helped teams reduce inefficiencies by 12%, cut bottlenecks by 15%, and build reporting systems that gave leadership real visibility into what was happening across their business.

I work with Power BI, Excel, SAP, and ERP systems and I am currently expanding into SQL. My approach is simple: find where the data is broken, fix the process behind it, and make sure the right people have the right information at the right time.

Based in Berlin. Fluent in English and German. Open to opportunities across Europe.
