Rockstar🎓
Top SchoolEduard Tudenhöfner is a Staff Software Engineer with 13 years of experience building and evolving distributed data systems, currently at Databricks and a PMC member and committer for Apache Iceberg. He focuses on backend engineering for lakehouse and catalog technologies—contributing to high-profile open-source projects like Apache Iceberg, Delta Lake, Presto, and Nessie—where he improves core APIs, metadata handling, and connector compatibility. His work shows deep expertise in schema/column-mapping edge cases, performance-sensitive Java services, and test automation practices, plus practical experience with Kubernetes operators and cloud-native database architectures. Eduard brings a track record of breaking monoliths into scalable components (Astra DB) and improving developer ergonomics through clearer documentation and cleaner test code. Colleagues rely on him for both hands-on implementation of tricky backend features (e.g., nested field metadata and UUIDType support) and for raising project code quality across ecosystems. Based in Stuttgart, he blends systems-level rigor with sustained, high-impact OSS stewardship.
