Worked on the rapidsai/cuvs repository to deliver a performance-oriented feature that enables real-time search reuse across multiple index types, including CAGRA, IVF-PQ, IVF-Flat, and Brute Force. Refactored search methods to accept shared references, allowing multiple searches without requiring index rebuilds and aligning the Rust API with established ANN libraries. Focused on algorithm optimization and data structures in Rust, the change improved throughput and reduced latency for production search workloads. Maintained comprehensive test coverage and updated documentation to reflect the new API ergonomics, resulting in reduced downtime and maintenance costs for high-volume, real-time search deployments.
