Description

Freelance Data Engineer from Bavaria.

I help teams solve concrete data problems - from data migration and automation to integrating AI where it truly adds value.

My strength lies in securely working with existing, often complex or flawed datasets: migrations, validation, automation of data quality checks, and integrating new data sources into established systems.

Whether it's a focused quick win (an automation script, a data pipeline, a working prototype in two weeks) or a long-term technical partner for a growing system: both are possible. I work at the pace your project demands.
