Freelancer Overview

I’m a freelance AI trainer with practical experience working on platforms like Data Annotation. My main job is to review AI responses to make sure they are accurate, helpful, and safe for users. I'm used to writing clear justifications (rationales) in English to explain why one response is better than another. I’m very detail-oriented, especially when it comes to fact-checking and spotting 'hallucinations' in the text. I enjoy this type of work and I'm always looking to improve the quality of the models I work with.
