Mahek Mishra developed a core feature for the goldmansachs/legend-engine repository, focusing on improving nested view handling within SQL query generation. She implemented logic for TableAliasColumn generation, enabling more reliable processing of depth-2 nested selects and enhancing the extraction of column aliases. Her work involved data modeling and rigorous testing to ensure robust integration with existing query planning, reducing the likelihood of runtime errors in complex queries. By adding comprehensive regression tests, Mahek strengthened test coverage and helped prevent future regressions. The project was completed using Pure and SQL, demonstrating thoughtful engineering depth within a focused development period.
