As a Bilingual AI Trainer & Evaluator at DataAnnotation, I engineered complex prompts and evaluated AI-generated responses to train and test Large Language Models (LLMs). I contributed to model fine-tuning and assisted in the creation of robust evaluation rubrics. My primary focus was ensuring the accuracy and cultural relevance of model outputs across English, Traditional Chinese, and Simplified Chinese. • Developed prompts in multiple languages to expand LLM capabilities. • Assessed AI responses for factual accuracy, tone, and cultural appropriateness. • Helped design evaluation criteria and quality benchmarks. • Played a crucial role in improving data quality for AI model development.
