Senior Data Annotator (Freelance)
As a Senior Data Annotator (Freelance), I accurately annotated images using bounding boxes, polygons, semantic segmentation, and key-point labeling for AI and Machine Learning models. I worked across remote platforms and specialized tools to complete high-complexity data labeling tasks, ensuring a consistent performance accuracy exceeding 98.5%. My responsibilities also included quality checking and providing constructive feedback on labeling guidelines. • Completed over 60,000+ 2D/3D image annotation and text sentiment analysis tasks. • Utilized multiple annotation tools including LabelImg, CVAT, and Prodigy. • Achieved "Gold" tier status on labeling platforms due to quality and reliability. • Collaborated with team leads to refine labeling protocols and reduce ambiguity.
