Freelancer Overview

AI Trainer Worked on multiple AI evaluation project types for more than one year, applying detailed project-specific guidelines and rubrics. Compared AI-generated responses for factual accuracy, instruction following, reasoning quality, clarity, formatting, safety, and overall helpfulness. Wrote clear rationales explaining why one response was stronger or weaker than another. Reviewed tasks involving STEM reasoning, mathematical problem solving, technical explanations, image evaluation, LaTeX/Typst formatting, multilingual content, and general response quality.Identified hallucinations, unsupported claims, calculation errors, weak reasoning, vague explanations, formatting issues, and failures to follow instructions. Developed strong familiarity with project workflows, onboarding materials, benchmark tasks, quality standards, reviewer expectations, and contributor best practices.
