Worked on the Eventual-Inc/Daft repository to deliver direct Delta Lake write capabilities to Unity Catalog, enabling streamlined data governance and catalog integration. Developed the daft.DataFrame.write_deltalake() method in Python, supporting multiple write modes such as append, overwrite with or without schema changes, and external table creation. Addressed compatibility issues by pinning the httpx library, ensuring stable interactions with unitycatalog-python. This work reduced manual ETL steps and improved catalog interoperability, allowing data engineering teams to efficiently manage and govern data assets. The project demonstrated depth in DataFrames, Delta Lake, and Unity Catalog integration, focusing on robust, maintainable engineering solutions.
