Freelancer Overview

CRYSTALYN JONES AI Generalist | Freelance AI Trainer | Data Evaluator | Ph.D. Mathematics & Computer Science | Remote Contributor [email protected] | United States | Remote / Freelance | Available Immediately Professional Summary I'm a Ph.D.-trained mathematician and computer scientist with a deep background in analytical reasoning, structured problem-solving, and rigorous written communication. I hold a doctorate from the University of Oregon and a Certified Advanced AI Data Trainer credential from AIDRALabs, and I've spent the years since graduation applying that foundation to real-world AI training and data annotation work — evaluating model outputs, writing rubric-based feedback, annotating text, images, and video, and contributing to the kind of high-quality training data that makes the difference between a model that is helpful and one that is confidently wrong. What I bring to this role isn't just technical ability — it's the habit of thinking carefully, explaining my reasoning in writing, and flagging uncertainty honestly rather than projecting false confidence. A Ph.D. in mathematics teaches you that the hardest part of any problem is usually not the computation — it's knowing whether you've actually answered the right question. That instinct is exactly what good AI evaluation work demands, and it's what I bring to every task I work on. I'm independent, reliable, detail-oriented, and genuinely curious about how AI systems are built and improved. Available imme
