Freelancer Overview

I am an experienced data annotation and AI training data specialist with a strong focus on text labeling, sentiment analysis, intent recognition, and entity tagging for NLP projects. I excel at following detailed guidelines, maintaining consistency across large datasets, and providing clear justifications for annotation and evaluation decisions. My work includes rating AI-generated responses for accuracy, relevance, and compliance, as well as cleaning and structuring data for quality assurance. I am proficient in tools such as Google Docs/Sheets, MS Office, and a variety of web-based labeling platforms including Welocalize, RWS, Clickworker, Remotasks, and TELUS International AI. I approach every project with careful attention to detail, reliable productivity, and a commitment to upholding high standards in data quality.
