Labeling Experience

AI Data Annotation & Labeling Specialist (Freelance/Contract)

CVATImageBounding Box

In this role, I annotated product images using bounding boxes, segmentation masks, and attribute tags for computer vision training pipelines. I ensured high annotation accuracy on batches exceeding 2,000 images while identifying inconsistencies and ambiguous edge cases. My responsibilities also included image content moderation and development of annotation guides. • Applied bounding box and segmentation techniques to product and fashion imagery • Delivered large batches to strict quality standards • Collaborated with project leads to improve annotation processes • Used platforms such as CVAT, Labelbox, and Surge AI
