Freelancer Overview

I have hands-on experience in data labeling and annotation, supporting AI training projects across text, image, and video datasets. My work has included tasks such as entity recognition, sentiment tagging, image classification, bounding box annotation, and video action tracking. Through these projects, I’ve developed a strong eye for detail, consistency, and accuracy—qualities that are essential for producing high-quality training data. In addition to technical precision, I bring adaptability and familiarity with a range of annotation tools and workflows. I understand the importance of following project-specific guidelines while maintaining efficiency under tight deadlines. My ability to quickly learn new labeling frameworks and apply consistent judgment makes me a reliable contributor to AI development teams.
