Freelancer Overview

I have hands-on experience in data labeling, annotation, and the curation of high-quality training datasets that power machine learning and AI systems. My work has spanned text classification, named entity recognition, image tagging, and RLHF (Reinforcement Learning from Human Feedback) tasks, the kind of nuanced, instruction-following evaluations that directly shape model behavior. I am detail-oriented and consistent in applying annotation guidelines, even in ambiguous or edge-case scenarios, ensuring the data I produce meets the quality standards required for model training and evaluation. What sets me apart is my ability to think critically about why a label is correct, not just what the label is, a mindset that improves inter-annotator agreement and overall dataset reliability. I am comfortable working with style guides, rubrics, and feedback loops, and I adapt quickly to evolving labeling schemas. I also bring strong written communication skills, which are especially valuable in tasks requiring response ranking, prompt writing, or evaluating AI-generated outputs for accuracy, helpfulness, and safety.
