Summary
👤
Senior🎓
Top SchoolZexi Han is a Staff R&D Engineer with a decade of experience building end-to-end perception and big-model algorithms for autonomous driving, currently focusing on camera object detection at Momenta. He has led dynamic LiDAR perception teams and shipped production-grade 3D detection and tracking systems that combine PointRCNN/PV-RCNN variants, optical flow attention, and real-time C++ preprocessing optimizations. Zexi’s background spans applied research and engineering across startups and research institutes, from creating large-scale annotated 3D datasets and bespoke labeling tools to deploying model pipelines in constrained embedded environments. Based in Shanghai, he blends hands-on deep learning, sensor fusion, and systems engineering with a track record of improving both accuracy and latency in safety-critical perception stacks. An interesting detail: he has repeatedly moved models from SOTA research into real-time product settings, achieving metrics like 0.93 AP on pedestrian detection through iterative annotation and algorithmic tuning.
