Worked on the alibaba/zvec repository over two months, delivering six new features focused on high-performance search and maintainability. Developed robust CPU feature detection to ensure AVX2 and AVX512_FP16 instructions were only used when supported, improving reliability across hardware. Optimized HNSW neighbor search with advanced filtering and unified the search path for maintainability. Integrated DiskANN core components, expanded Euclidean search capabilities, and enhanced cross-platform support, including macOS. Improved benchmarking tooling and documentation to streamline onboarding and testing. Leveraged C++, CMake, and SIMD optimization techniques throughout, emphasizing performance engineering, code cleanliness, and measurable business value in search quality and responsiveness.
