Bounding BoxYou performed high-volume image and video annotation to support computer vision model training using precise bounding boxes, polygon/semantic segmentation, and keypoint mapping. You followed strict labeling guidelines and collaborated with machine learning engineering teams to refine annotation rules and handle complex edge cases. You executed rigorous QA through self-review and peer verification, maintaining accuracy above 98.5% while meeting operational deadlines. • Annotated thousands of high-resolution images and complex video sequences daily. • Labeled bounding boxes, polygon/semantic segmentation, and keypoints using CVAT, Labelbox, and internal tooling. • Worked directly with ML teams to improve guidelines and resolve edge cases. • Performed self-QA and peer evaluations to reduce labeling errors.
