Image annotation
I worked as a Freelance Data Annotator on technology and manufacturing projects where I successfully supported the development of computer vision datasets used for industrial automation, predictive maintenance, and worker safety monitoring systems. I completed a wide range of annotation tasks including object detection, polygon segmentation, mechanical defect classification, and identification of safety compliance across more than 25,000 industrial images. I delivered annotations in COCO, Pascal VOC, and JSON formats and consistently achieved over 97% accuracy by following detailed guidelines, performing structured self-reviews, and collaborating with clients to refine labeling requirements.
