Xiao Zhang is a seasoned computer scientist and software engineering leader with 11 years of experience building large-scale, production systems across companies like Meta, Twitter, Pinterest, Airbnb, and Thumbtack. He holds a Ph.D. in Computer Science and has led both hands-on engineering and people management roles—driving initiatives from real-time ads and anti-spam systems to shopping catalogs and privacy infrastructure. At Thumbtack he architected high-impact features (Jobs Feed, geo-targeting, ranking models) that measurably increased revenue and engagement, and at Twitter he built the company’s first automated compromised account detection framework. Comfortable across backend services, search and machine-learning informed ranking, his work blends rigorous research training with practical product impact. Based in San Francisco, he combines technical depth in distributed systems and information retrieval with proven cross-functional leadership. An under-the-radar strength is his track record of turning experimental models and indices into robust, real-time services that scale.
