Freelancer profile translated to English.

Description

I am a doctor in data science and support companies in strategically developing their data landscape: from inventory analysis and the construction of scalable BI architectures to AI-supported automation. My focus is on integrating heterogeneous data sources, developing data models and dashboards, and deriving concrete recommendations for action from complex data. I bring experience from industries such as banking & insurance, manufacturing, healthcare, and logistics. What sets me apart: I combine analytical depth with change management expertise. In addition to technical implementation, I support teams through workshops and training to ensure data-driven work becomes sustainably embedded.
