Senior🎓
Top SchoolCai Gao is a Staff Data Scientist and operations research expert with eight years of experience applying mathematical programming, heuristics, and network optimization to large-scale supply chain and logistics problems. Based in San Jose, he led development of production optimization engines at Walmart Global Tech—most notably a 3D bin-packing palletization system delivering >85% efficiency and a stable inbound network optimizer that can replace commercial tools. His background includes building BCG’s SNOW AI supply-chain optimization product and identifying multimillion-dollar transportation savings for major manufacturers and retailers. Cai combines strong software engineering skills (Java, Python, C++, Springboot, SQL) with solver expertise (CPLEX/Gurobi) to move models from research to pilots and production. He holds a PhD in Operations Research and has applied his academic work—from UAV routing to explainable constraint-based ML—directly to industry problems. Notably, he blends theoretical rigor with pragmatic heuristics to deliver robust, explainable optimization systems that scale.
