Summary
🤩
Rockstar🎓
Top SchoolUwe Korn is a data engineer and scientist with 17 years of experience building scalable Python-based data systems and tooling from Karlsruhe, Germany. As CTO @Quantco and a core maintainer on projects like conda-forge, he blends hands-on engineering with infrastructure and automation expertise—improving CI/CD, packaging, and cross-platform builds. Uwe is an active Apache Arrow and Parquet PMC contributor who has worked on performance-sensitive Arrow↔Parquet interop and on improving Parquet/Arrow handling across pandas, Dask, and DataFusion. His work often sits at the intersection of data formats, high-performance IO, and reproducible environments, reflected in contributions to pandas, mamba, and repo2docker. He brings a practical QA and test-automation mindset (mamba) and a strong documentation/UX focus (conda-forge, BinderHub) that helps make complex systems reliable and approachable. Colleagues know him for quietly fixing tricky memory and compatibility issues that unlock faster, more robust analytics pipelines.
