Freelancer Overview

I am a skilled Data Labeling Specialist with extensive experience annotating and validating a wide range of datasets to support machine learning and AI development. My expertise covers image, text, audio, and video annotation, including tasks such as bounding box creation, segmentation, keypoint detection, sentiment analysis, entity extraction, and generating chatbot responses. I have practical experience using tools like CVAT and Excel, and I excel at data validation, product categorization, and structuring metadata for both e‑commerce and natural language processing projects. I work closely with data scientists and project managers to ensure precise labeling, resolve ambiguities, and streamline workflows, always upholding the highest standards of data quality and security. My educational background in computer linguistics further enhances my ability to work effectively with complex language and AI training data.
