Freelancer Overview

I am a native Japanese professional with hands-on experience in data labeling, annotation, and AI training data projects, particularly in natural language processing tasks. My work includes transcribing Japanese audio with mixed script for Open Train AI using tools such as Labelbox, as well as evaluating chatbot responses and machine translations for accuracy, fluency, and relevance with Appen and Data Annotation.In addition, I participated in a Japanese image data collection project with TELUS International, capturing and submitting high-quality images of various document types, including books, newspapers, receipts, research papers, handwritten notes, and medical documents. With a background in web content creation and data processing, I bring strong attention to detail, consistency, and quality control to every project, and I am comfortable working remotely while leveraging my bilingual Japanese–English skills and technical abilities in database management and web development to contribute effectively to AI and data-driven initiatives.
