Freelancer Overview

With over five years of hands-on experience in data labeling and AI training, I’ve contributed to a wide range of projects involving image, video, text, and audio annotation. My expertise spans 2D and 3D formats, including bounding boxes, semantic segmentation, and text classification. I’ve worked across platforms like Remotasks, Upwork, Clickworker, and CloudFactory, consistently delivering high-quality annotations tailored to project-specific guidelines. As a team captain at CloudFactory Kenya, I led a group of 42 annotators, ensuring operational efficiency, mentoring new members, and maintaining top-tier quality standards.
