Senior Data Labeling & QA Specialist

RemotasksImageBounding Box

As a Senior Data Labeling & QA Specialist, I annotated over 50,000 images monthly for object detection, using bounding boxes and polygons in support of autonomous vehicle and robotics projects. I maintained a consistent annotation accuracy rate above 98%, ranking in the top tier of contributors. I audited peer annotations, provided structured feedback, and collaborated with project leads to refine ontologies. • Carried out semantic segmentation and complex image annotation tasks. • Reviewed 500–800 tasks per day and produced structured guidelines. • Helped reduce inter-annotator disagreement by 22% over multiple cycles. • Supported multilingual data labeling for conversational AI, including English and Swahili.
