AI Data Specialist — Data Annotator & Validator
As an AI Data Specialist and Data Annotator at RWS Moravia (TrainAI Community), I annotated and labeled multimodal AI training data including text, image, and video datasets. My primary responsibility was to facilitate the development and fine-tuning of large language models and machine learning systems through high-quality data annotation. I performed both annotation and validation, ensuring all training data met enterprise accuracy and consistency standards. • Performed object detection, landmark labeling, attribute tagging, and image segmentation for computer vision models. • Conducted video annotation including object tracking, scene classification, and frame-by-frame labeling. • Evaluated semantic similarity, intent classification, and response quality for NLP model training. • Applied human-in-the-loop validation processes to provide expert feedback for model reliability and reduction of bias.
