Contributed to the goldmansachs/legend-engine repository by engineering enhancements and targeted fixes for data lineage, grammar parsing, and backend reliability. Delivered lineage tracking improvements for semi-structured data and TDS queries, enabling more accurate tracing of data origins and transformations in relational and model-driven contexts. Addressed complex parsing issues by refining grammar generation for enums with spaces and corrected SQL casting for MemSQL float handling, reducing downstream errors and improving data accuracy. Leveraged Java, SQL, and JSON across backend development, code generation, and testing, demonstrating a methodical approach to governance, audit readiness, and robust data pipeline traceability within enterprise systems.
