Labeling Experience

Data Annotator

CVATImageBounding Box

I labeled and annotated images, videos, and text datasets for AI training and validation. Using CVAT and Bliss Way, I drew bounding boxes, polygons, and segmentation masks on both 2D and 3D data. I worked closely with QA teams to ensure high-quality annotations and improved workflow efficiency. • Achieved over 95% accuracy through validation and error checking. • Managed large datasets under tight deadlines while maintaining precision. • Suggested improvements to annotation guidelines to reduce errors. • Protected sensitive data and adhered to strict privacy policies.
