I work on vector similarity search for billions-scale databases, including inverted index techniques for sparse vectors, and product quantization for dense vectors.My team of four researchers has partnerships with dozens of product teams across the company, transforming tens of millions of dollars worth of cpu cycles into billions of dollars of marginal revenue for Search Ads, Display Ads, Shopping, Play, and others. We also drive non-revenue strategic impacts like Android's Playing Now", and YouTube's ContentID copyright detection system.Two Google "Perfy" awards for economically significant performance optimizations. One for optimizing an AVX2 product quantization scoring routine, and another for optimizing posting-list co-retrieval.
