Freelancer Overview

I am a bilingual Japanese–English professional with hands-on experience in AI data annotation and quality assurance across text, audio, and multilingual datasets. My work includes Japanese audio transcription, text tagging, data labelling, and annotation review used in speech recognition, large language models (LLMs), and natural language processing (NLP) training pipelines. In addition to linguistic annotation, I have experience testing and evaluating Web2 and Web3 applications, assessing user experience, validating functionality, and reporting usability or accuracy issues through structured feedback. I am familiar with blockchain, crypto, and DeFi terminology, enabling me to contribute effectively to domain-specific AI training and evaluation tasks in emerging technology areas. I am detail-oriented, reliable, and highly skilled at following complex English guidelines, consistently delivering high-accuracy, quality-controlled data that meets strict model training and QA standards in remote, production-level AI environments.

This project involved large-scale Japanese and English speech data collection for AI speech recognition and natural language understanding. I participated through Appen, Clickworker, and various client organisations on Upwork.

Specific tasks involved recording clear, high-quality audio clips according to prompts. Each project typically included several hundred to several thousand utterances. Quality measures focused on following precise English instructions, maintaining consistent recording conditions, minimizing background noise, and re-recording segments flagged by automated quality checks. All submissions were reviewed and validated by the client or platform before approval.
