Zeyuan Yu is a tech lead based in New York with a decade of experience building scalable testing and CI/CD systems for complex robotics and autonomous-driving stacks. He led design and implementation of end-to-end HIL testing ecosystems and labeling workflows at Cruise that turned multi-week release processes into hours and scaled simulation testing across perception, training, and release use cases. Comfortable in both low-level driver work and high-level automation, he also contributed backend improvements and plugin testing to the widely used Apache Traffic Server open-source project. A hands-on leader, he blends systems thinking with practical pathways from manual to fully automated workflows and a knack for thoughtful tooling that developers actually use. Outside engineering he presses shutters, shapes clay, and climbs rocks—habits that surface in his curiosity-driven approach to problem solving.
