Freelancer Overview

I am a bilingual English–Mandarin AI Trainer with experience in data labeling, machine translation evaluation, and linguistic quality assurance. I specialize in training and evaluating AI language models for accuracy, fluency, and cultural relevance. My background in translation and interpretation allows me to ensure nuanced understanding between English and Mandarin content, enhancing the contextual performance of AI systems. Previously, I supported cross-cultural communication as a translator and interpreter in academic and exhibition settings, where I honed my attention to linguistic detail and clarity. With a strong foundation in law and linguistics, I bring analytical precision, adaptability, and a deep understanding of language structure to AI training and data annotation projects.

This ongoing project focuses on generating and refining Mandarin-language prompts and responses for fine-tuning large language models. I create, translate, and evaluate AI-generated text to ensure linguistic accuracy, contextual fluency, and cultural appropriateness in both Mandarin and English. Tasks include prompt design, response classification, translation quality assessment, and comparative rating of AI outputs. I also provide linguistic feedback to improve the model’s understanding of idiomatic expressions and bilingual semantics. All data labeling tasks adhere to strict quality assurance protocols, including consistency checks, peer review, and adherence to detailed annotation guidelines. The project contributes to enhancing model alignment and natural language understanding for bilingual users.
