Freelancer Overview

I have over five years of experience working in AI training and data labeling, mainly with text-based datasets used to train and evaluate language models. My work includes annotating large volumes of data, evaluating AI-generated responses, ranking outputs, and checking content for accuracy, clarity, safety, and instruction-following. I am comfortable working with detailed guidelines and consistently deliver high-quality labels while meeting productivity targets. What sets me apart is my strong understanding of how language models behave and how human feedback improves their performance. I have worked on projects involving conversational AI, content safety, sentiment and intent classification, and answer quality scoring. I pay close attention to edge cases, flag unclear examples, and provide useful feedback to improve annotation quality. I am detail-oriented, reliable, and able to adapt quickly to new tools and evolving AI training standards.
