Worked on the ray-project/deltacat repository to deliver Rivulet data processing integration within deltacat.storage, enabling seamless storage abstractions for Arrow, Feather, and Parquet formats. Focused on Python-based data engineering, the work included implementing robust schema management, data serialization, and file I/O capabilities. Enhanced the Dataset and Schema modules with a from_pydict constructor and PyArrow type conversions, including int64 support, to streamline data ingestion and improve type guarantees. Expanded unit and integration tests to ensure reliability and maintainability, resulting in all tests passing and no critical defects reported. The updates strengthened dataset creation workflows and improved overall system design.
