Senior🎓
Top SchoolLongyu Zhao is a Senior Machine Learning Engineer with a PhD and over nine years of experience building production ML and robotics systems across Amazon, AWS AI, and Pinterest. He combines deep research expertise in reinforcement learning and offline evaluation with hands-on engineering—contributing to AWS RoboMaker WorldForge, shipping RL tooling and Sagemaker examples, and authoring Docker and SDK integrations for reproducible workflows. At Amazon he invented an automatic singulation system (4 granted patents) now saving the company over $50M annually, and has led applied RL projects for recommendation, industrial control, and finance. Currently at Pinterest he focuses on ads retrieval and targeting, bridging scalable ML infrastructure with product-facing models. Longyu’s background in physics and engineering gives him a strong quantitative foundation, and he’s notable for turning simulation and research prototypes into daily-tested, deployable systems.
