Freelance Data Annotation Specialist
As a Freelance Data Annotation Specialist at CVAT and OpenTrain AI, I annotated over 5,000 video frames for sports analytics projects in volleyball, soccer, and tennis. I specialized in labeling only active objects, such as the ball during play, while maintaining over 90% accuracy, especially on blurry and fast-moving objects. My workflow included self-auditing with platform QA metrics and successfully completing multiple one-time projects with zero rework requests. • Annotated active objects for real game scenarios and ignored non-relevant objects. • Consistently delivered projects with a high accuracy rate above 90%. • Completed more than 10 one-time projects with no rework required. • Used advanced video annotation tools and conducted quality control before submission.
