Freelancer Overview

I have hands-on experience in AI training data projects involving transcription, translation evaluation, response evaluation (RLHF), and voice recording across Malay, Chinese, and English. My work includes transcription tasks for Malay on OneForma, translation (Chinese-Malay) and content evaluation for Crowdgen/Appen, and AI model response evaluation in both Chinese and Malay for Outlier.AI. Additionally, I participated in a Chinese voice recording project for Outlier.AI to support speech recognition model development. These roles required high linguistic accuracy, attention to detail, and consistency in tone and context across multiple languages. With a strong foundation as a former Senior Legal Associate, I bring advanced analytical and problem-solving skills, precision in documentation, and cross-cultural communication experience. I am fluent in Mandarin, English, and Malay, with proficiency in Japanese (JLPT N3, preparing for N2). Proactive in continuous learning, I am also self-studying Python to strengthen my technical understanding in AI and data-related fields.
