Expertise: combination of infra, AI/ML, product and analytics, with deep domain knowledge of ads ecosystem, search and integrity.Leadership: 10+ years tech lead and 6+ years people manager experience, successfully founded and scaled engineering teams in Google, TikTok, Pinterest, and startup.With 15+ years engineering experience, increased monetization revenue and customer success by initiating/delivering a range of products (audience targeting, lookalike modeling, pacing, signal loss mitigation, brand safety, etc), enhancing recommendation system (applied ML, user modeling, signal modeling, ranking algo, etc), as well as building infra for serving stack with very high QPS (YouTube ads and Google Display ads overall traffic) and large-scale data processing.I believe that "math + infra" is the power of exploring the world, and AGI (artificial general intelligence) would empower human civilization.
