Freelancer Overview

I am a bilingual AI data annotation specialist with hands-on experience in multilingual LLM training, model tool-call evaluation, and prompt/response quality assessment in both English and Mandarin Chinese. My background includes contributing to large-scale AI training projects via Data Annotation and Mercor, where I reviewed, labeled, and evaluated diverse datasets—ranging from enterprise and consulting data to chatbot content—ensuring high accuracy, cultural appropriateness, and adherence to complex guidelines. With an MBA in Business Analytics and over nine years of professional interpretation and translation, I bring a strong analytical mindset, cross-cultural expertise, and a proven track record of delivering high-quality, guideline-compliant data annotation and quality assurance in remote, self-directed environments.
