Freelancer Overview

I am a seasoned business professional with over 30 years of extensive experience in international trade, insurance sales, and marketing. Based on my deep expertise in the financial and trade sectors, I provide high-quality data labeling and RLHF (Reinforcement Learning from Human Feedback) evaluation services. My background in managing complex export operations and corporate insurance allows me to process domain-specific data with a high degree of accuracy and contextual understanding that goes beyond simple data entry. As an advanced English speaker with a Bachelor's degree in International Trade, I specialize in cross-lingual data verification and English-to-Korean localization. I am particularly adept at evaluating LLM responses for logical consistency, professional terminology, and business etiquette. My goal is to leverage my decades of professional insight to help build sophisticated AI systems that require nuanced human judgment and specialized industry knowledge.
