Worked on the antgroup/vsag repository to deliver two major features focused on ARM architecture performance. Over two months, implemented ARM NEON SIMD acceleration by introducing NEON-enabled functions, updating the CMake-based build system, and expanding automated test coverage to ensure release readiness. Further optimized ARM vector operations by improving SQ8 instruction per cycle efficiency and adding cache prefetching for L1, L2, and L3, which enhanced runtime performance and potentially reduced build costs. The work demonstrated expertise in ARM Assembly, C++, and performance tuning, with a strong emphasis on SIMD optimization and vectorization, though no bug fixes were recorded.
