Worked on the Velox project, focusing on enhancing the QuantileDigest component to support generic distribution range types. Refactored the getDistributionFunction to accept generic type parameters for range boundaries, improving type safety and consistency throughout the codebase. Updated associated unit tests in C++ to validate the new type system, ensuring robust coverage. Addressed correctness by implementing a targeted fix for empty Q-Digests, modifying the distribution logic to return deterministic results and preserve invariants for downstream analytics. Collaborated through code reviews and maintained minimal disruption to existing quantile logic, demonstrating strong skills in C++, algorithm design, and software engineering practices.
