I also have extensive experience in Japanese-English translation and transcription, contributing to the development of accurate multilingual AI systems. With a master’s degree in Machine Learning from Keio University and a strong background in IT service management, I bring both technical expertise and linguistic accuracy to every project. I have also delivered over 3,000 clean, high-quality voice recordings for AI voice model training, leveraging my skills in narration and dialogue delivery. My goal is to contribute to the creation of user-centered AI systems that combine technical precision with cultural and linguistic depth.
