I worked as a data annotator on an image annotation project with Appen. The scope of the project involved labeling and annotating visual objects within images to support computer vision model training. My tasks included object identification, bounding box annotation, and accurate classification of image elements based on detailed project guidelines. The project involved annotating a large dataset consisting of thousands of images, requiring consistency and attention to detail across repeated labeling tasks. Quality was measured through regular accuracy checks, gold-standard comparisons, and reviewer feedback, with strict adherence to annotation guidelines. I maintained high accuracy scores by carefully reviewing each image and correcting labels based on quality audits and updated instructions.
