I worked as a data annotator focused on labeling, organizing, and managing datasets for machine learning projects. My role included tagging objects in images, classifying text, and reviewing AI-generated outputs for accuracy. I used CVAT and proprietary tools to ensure high data quality for AI systems. • Labeled images using bounding boxes and segmentation tools • Classified text for sentiment analysis and intent detection • Reviewed and corrected AI outputs according to strict guidelines • Ensured annotation consistency across multiple data types
