I worked on a data labeling project focused on preparing image and text data for machine learning models. The task involved tagging images, drawing bounding boxes, and labeling text for things like sentiment, intent, and categories, following clear guidelines. Accuracy and consistency were very important, so each task was carefully reviewed, and feedback was applied to improve quality. The labelled data was used to train and improve AI models for better performance.
