Freelancer Overview

I am an experienced AI data annotation specialist and agent evaluation analyst with a strong track record of achieving over 98% accuracy in data enrichment, labeling, and quality assurance across platforms like Appen, Outlier.ai, and UHRS. My expertise includes working with CVAT for image and text annotation (polygon and bounding box), semantic evaluation, and handling multilingual datasets, especially in Tamil and English. I have enriched and QA-tested thousands of datasets in domains such as e-commerce, healthcare, and sales research, using tools like JSON, YAML, Python, and Power BI. My background also includes sales data analysis and market trend research, and I am currently expanding my skills in prompt engineering and advanced analytics to further enhance machine learning datasets.
