Freelancer Overview

A detail-oriented AI practitioner with hands-on experience collaborating with large language models (Claude, ChatGPT) to build end-to-end data applications — from prompt engineering and output evaluation to iterative refinement. My background in data processing (MATLAB, Python, Excel) has given me a strong command of the full data pipeline: scraping, cleaning, structuring, and quality-auditing — skills directly transferable to dataset construction, annotation, and AI output evaluation. I have authored 4+ industry research reports and 60+ data-driven briefings, demonstrating the ability to systematically assess text for logical coherence, factual accuracy, and expression quality. What sets me apart is my trilingual proficiency (Native Simplified Chinese, Fluent English with IELTS 7.0, Proficient Traditional Chinese), enabling me to evaluate AI-generated content across languages for naturalness and cultural appropriateness. Combined with my domain expertise in supply chain management and my deep familiarity with advanced prompting techniques (Chain-of-Thought, Few-shot Prompting), I am well-positioned to deliver high-quality RLHF feedback, multilingual corpus annotation, and domain-specific instruction design — all on a flexible, remote part-time basis.
