Video Annotation Specialist (Freelance / AI Data Projects)

CVATVideoSegmentation
As a Video Annotation Specialist, I annotated complex video sequences featuring human-object interactions and motion tracking. I segmented actions into precise intervals and labeled object manipulations such as pick, place, adjust, and release. I ensured strict adherence to annotation guidelines and delivered datasets used for computer vision model training. • Maintained frame-level accuracy across long video sequences • Developed scalable, structured labeling workflows • Delivered high-quality, annotation-ready outputs • Collaborated with AI teams remotely
