Data Annotation Specialist / AI Trainer
As a Data Annotation Specialist and AI Trainer at Revelo, I annotated and labeled high volumes of text, image, and sentiment data to directly train and optimize various AI models. My work demanded strict adherence to rigorous quality standards and detailed project guidelines, supporting model improvement through precise, iterative annotation and collaboration with developers. I ensured data consistency and accuracy while utilizing Revelo's annotation platform to streamline processing for scalability. • Labeled data included natural language text, images, and sentiment samples across multiple projects. • Performed iterative quality checks and re-labeling to enhance AI model accuracy. • Specialized in Named Entity Recognition (NER), sentiment analysis, and text/image classification tasks. • Coordinated with project teams to refine annotation protocols and resolve complex cases.
