Freelancer Overview

I am experienced in data labeling, annotation, and AI training data evaluation, with a strong background in structured data analysis and quality assurance. My work includes classifying and annotating text data for AI model evaluation, applying detailed guidelines and scoring rubrics to ensure accuracy and consistency. I have hands-on experience manipulating large e-commerce datasets, validating sales and stock data, and systematically identifying anomalies and errors using advanced Excel functions, Google Sheets, and platforms like Shopify and Zedonk. My approach emphasizes precision, rule adherence, and clear documentation, and I am comfortable with logic-based tasks using basic Python and JavaScript. I am passionate about delivering high-quality, reliable data to support AI training and business decision-making.
