Worked on backend stability and data quality for the panther_analysis_tool repository, focusing on targeted bug fixes over a two-month period. Addressed SQL table name validation by refactoring the CTE alias extraction logic and introducing a modular get_aliases helper, which improved the accuracy of SQL parsing and reduced false positives in validation checks. Later, resolved a filtering issue affecting experimental detections by correcting the merging of default and user-defined status filters, enhancing workflow reliability for analysts. Utilized Python for backend development, emphasizing code refactoring, SQL parsing, and unit testing to ensure maintainable, robust solutions that improved downstream analytics reliability.
