Worked on large-scale AI training datasets involving image, video, and LiDAR data. Responsible for both annotation and quality assurance, ensuring datasets met strict client and model requirements. Key responsibilities included 2D bounding boxes, polygons, semantic segmentation, keypoints, object tracking, and 3D cuboid annotation for LiDAR point clouds. Performed QA/QC reviews, identified inconsistencies, corrected errors, and provided feedback to improve annotation accuracy and consistency. Used industry tools such as CVAT, Labelbox, V7 Darwin, and Supervisely, following detailed annotation guidelines and delivery timelines. Achievements: Reviewed and validated more than 20,000 of annotated images, videos, and LiDAR frames with high accuracy Reduced annotation errors by performing systematic QA checks before final delivery Handled complex edge cases and occlusions in 2D and 3D data Consistently met tight deadlines while maintaining quality-first standards Contributed to production-ready datasets used in computer vision and autonomous driving models
