Freelancer Overview

I am a native Japanese speaker with a Master’s degree in Applied Chemistry and hands-on experience in AI data annotation, prompt evaluation, and quality assurance for large language model (LLM) training. My background includes over four years of tutoring and academic support, where I developed strong skills in technical writing, proofreading, and data analysis using machine learning methods. I have worked on projects evaluating and editing AI-generated responses in both Japanese and English, ensuring their fluency, relevance, and accuracy according to strict guidelines. I am passionate about contributing to responsible AI development by generating and evaluating high-quality, context-aware training data, and I am comfortable working with complex editorial standards and sensitive content.
