Freelancer Overview

I have several years of experience working as a data evaluator and auditor for leading AI training data companies, including Appen and Lionbridge.

I am skilled in assessing the relevance and suitability of online content according to detailed guidelines, and have worked extensively with platforms like Facebook and Instagram. I am highly proficient with Microsoft Office, especially Excel, and have experience using statistical tools such as Minitab and R. My strong attention to detail, ability to work independently, and commitment to meeting deadlines have allowed me to consistently deliver high-quality labeled data for AI and machine learning projects.
