Data Labeling & Annotation (Freelance / Self-Trained Projects)
Performed both text and image annotation tasks in line with structured AI training frameworks. Labeled datasets specific to classification, sentiment analysis, and categorization for high-quality machine learning development. Maintained exceptionally high accuracy and consistency across large-scale tasks with regular quality review. • Utilized tools such as Labelbox and CVAT or equivalent for annotation tasks. • Applied bounding box annotation for images and objects. • Engaged in named entity recognition and text-based sentiment tagging. • Enforced data integrity and adapted to evolving labeling instructions.
