Data Collection & Annotation Specialist (Freelance)
As a freelance Data Collection & Annotation Specialist, I captured point-of-view videos of manipulation-intensive household tasks strictly following AI training dataset requirements. My responsibilities included quality control, structured annotation review, and batch-processing large volumes while maintaining high accuracy. I corrected structured classification outputs and flagged systematic errors to support label guideline evolution. • Recorded and uploaded task-specific, high-quality video datasets using a head-mounted setup. • Performed detailed annotation review and applied corrections using CVAT and Label Studio. • Processed and verified 200–500 items per session, ensuring adherence to task variance and accuracy targets. • Communicated error types and dataset structure insights to support ongoing model improvement.
