AI Data Annotation Specialist
As an AI Data Annotation Specialist, I supported major machine learning and artificial intelligence model training projects. My responsibilities included annotating and labeling large datasets for computer vision, NLP, and LLM workflows while maintaining strict accuracy and productivity targets. I worked across varied data modalities and platform environments to deliver high-quality, labeled data. • Performed image annotation including bounding box, polygon segmentation, and object/classification tagging. • Completed NLP entity recognition and sentiment analysis labeling tasks. • Conducted quality assurance, dataset review, and correction of labeling inconsistencies. • Used platforms such as Labelbox, Appen, Remotasks, Scale AI, SuperAnnotate, Toloka, and TELUS AI.
