During July 2025, contributed to the IBM/velox repository by developing a seeded xxhash64 function for the Presto SQL dialect. This feature enables deterministic hashing of binary input by introducing a bigint seed argument, supporting consistent sharding and partitioning across distributed queries. The implementation focused on C++ development, leveraging expertise in database functions and hashing algorithms to ensure reproducibility and compatibility with Presto. By allowing users to specify a seed, the function improves partition stability and cache-hit rates, addressing the need for reliable analytics results in distributed environments. The work was delivered as a feature pull request and integrated into the codebase.
