Labeling Experience

Data Annotation Specialist (Video Annotation and Object Tracking)

CVATVideoBounding Box

I executed frame-by-frame bounding box annotation and object tracking for AI video datasets. Responsibilities included handling dynamic scenes and annotating fast-moving and occluded objects. I maintained accuracy and consistency using professional annotation tools. • Applied bounding box annotation for object detection and tracking • Performed frame-level tracking in challenging video scenarios • Maintained annotation standards for evolving project needs • Utilized CVAT and mobile video recording tools for data labeling
