Top SchoolEthan Liu is a software engineer with eight years of professional experience and a deep 13-year background in C++, systems design, and large-scale distributed infrastructure. He has built recommendation and ads infrastructure at TikTok, Meta, Google, and Microsoft, blending machine learning, privacy-conscious feature design, and operational excellence. Unusually, he holds three separate MS degrees spanning computer science, industrial & systems engineering, and transportation-focused civil engineering, which informs his strengths in mathematical modeling and systems thinking. Based in Sunnyvale, he pairs strong cross-functional communication with hands-on engineering, and—quirkily—still prefers developing in NetBeans while shipping production-grade systems at major tech platforms.
