Senior Data Labeling Specialist
As Senior Data Labeling Specialist, I led a team of 15 annotators labeling computer vision and NLP datasets for autonomous vehicle and chatbot AI projects. I ensured annotation standards and quality assurance with an average quality score of 98.7% over 200,000+ annotations. I coordinated with ML engineers to optimize schema, address edge cases, and audit data labeling outputs. • Managed complex labeling including 3D bounding boxes, polyline annotation, multi-label classification, and entity relationship tagging • Developed annotation guidelines reducing inter-annotator disagreement by 40% • Conducted regular audits and mentored junior labelers, improving team accuracy from 92% to 97%. • Specialized in advanced annotation such as semantic segmentation and text classification.
