Senior🎓
Top SchoolQiaoan Chen is a Staff Software Engineer with 13 years of experience building large-scale ML and autonomous driving systems, currently shaping end-to-end planners at DiDi. He holds a master’s from Tsinghua and has led production ML efforts at Pony.ai and Tencent, applying imitation learning and deep planners for complex driving scenarios and web-scale user behavior modeling for over a billion users. His work at Tencent delivered embedding- and GNN-driven features that notably boosted ad interaction and fraud-detection recall, and he implemented incremental item-based collaborative filtering serving hundreds of millions. Comfortable across distributed systems, graph representation learning, and real-world ML pipelines, he moves models from research into latency- and scale-constrained production. Colleagues note his appetite for hard algorithmic challenges and his tendency to blend system engineering rigor with probabilistic modeling insights. Based in Guangzhou, he brings both academic depth and repeated production impact in social, ad, and autonomous-driving domains.
