• Annotated and audited large-scale 3D point cloud and 2D bounding box datasets for the ZOOX Autonomous Vehicle project, directly contributing to a 98%+ accuracy benchmark for real-world object detection.
• Processed and labeled multi-modal sensor streams including LiDAR, Radar, and LWIR Thermal data to identify radiated heat signatures and spatial depth, enabling zero-visibility obstacle detection for autonomous navigation.
• Executed frame-by-frame annotation of pedestrian gesture sequences for Human-Robot Interaction (HRI) use cases, powering safer vehicle-to-pedestrian communication logic in AV decision-making systems.
• Performed pixel-level semantic segmentation of dynamic objects and infrastructure elements to support development of production-grade deep-learning scene-understanding models.
• Led systematic QC audit cycles across existing annotation datasets; identified and corrected labeling errors, measurably reducing downstream ML model training failures and improving dataset integrity.
• Managed daily task allocation and throughput for annotation teams, ensuring 100% on-time delivery of verified, high-quality datasets to client engineering teams.
• Applied expertise in day/night mode and infrared (LWIR) data analysis for object recognition pipelines, broadening the performance envelope of AV perception models across diverse environmental conditions.
