I am an experienced AI trainer and evaluator specializing in literacy, writing quality, fitness, and nutrition domains. With nearly two decades across education, publishing, and the fitness industry, I have developed strong skills in rubric-based evaluation of large language model outputs, ensuring high standards of accuracy, clarity, and bias mitigation. My work includes training and assessing AI responses for instruction-following and content quality, drawing on my background as a literacy specialist and author of over 100 books. I bring keen attention to detail, expert judgment, and a commitment to delivering reliable, high-quality training data for AI systems.
