Worked on the typesense/ClickHouse repository to address a critical bug in the gamma function, focusing on improving numerical reliability for analytics workloads. Applied expertise in C++ and error handling to ensure the lgamma function now returns NaN for negative integer inputs, preventing incorrect results in user dashboards and queries. Developed comprehensive unit tests in C++ to validate behavior across negative integers, zero, and positive integers, enhancing regression protection and traceability. Emphasized robust testing practices and clear commit documentation, resulting in improved reliability for mathematical functions within the codebase. The work strengthened the foundation for accurate analytics and data processing.
