Freelancer Overview

With a strong background in English–Japanese localization, QA, and linguistic data annotation, I have over 10 years of experience delivering high-quality translations and cultural adaptations for global tech companies. My recent work includes AI model training and evaluation projects focused on improving Japanese language performance and naturalness in LLMs. I specialize in linguistic quality assurance, prompt evaluation, and culturally aware data labeling. Combining my attention to detail with a deep understanding of cross-cultural communication, I ensure AI systems produce accurate, natural, and inclusive outputs for diverse audiences.
