Data Annotator
As a Data Annotator at Zone 01 in Kisumu, Kenya, I accurately labeled and annotated over 10,000 images, videos, and text entries for use in computer vision and NLP projects. I applied various annotation techniques, including bounding boxes, polygons, semantic segmentation, key points, and classification tags. My responsibilities included collaborating with data science teams and conducting thorough quality assurance on annotated datasets. • Labeled images, videos, and text for AI and machine learning models • Used industry tools such as Labelbox, CVAT, Label Studio, SuperAnnotate, V7, Roboflow, Amazon SageMaker Ground Truth, and Scale AI • Maintained high annotation accuracy and addressed edge cases by refining guidelines • Ensured data consistency and quality while processing high data volumes under tight deadlines.
