Freelance Data Annotator
As a Freelance Data Annotator, I labeled large-scale image, video, audio, and text datasets for AI and machine learning projects. I utilized bounding boxes, polygons, semantic segmentation, and keypoint annotations to support model training. My work involved strict adherence to client guidelines and maintaining quality scores above 98% across all major projects. • Applied annotation types including bounding boxes and polygons to images and video frames using Labelbox and CVAT. • Labeled text datasets for Named Entity Recognition (NER), sentiment tagging, and intent classification. • Transcribed and performed quality assurance for audio datasets in speech-to-text workflows. • Collaborated with teams to review and resolve ambiguous data labeling cases as needed.
