Freelancer Overview

I am an AI/LLM data specialist with over two years of hands-on experience creating, annotating, and evaluating high-quality English conversational datasets for large language model training. My expertise spans response quality scoring, safety and coherence assessment, RLHF support, and prompt engineering, with a strong focus on producing clean, natural, and contextually accurate data. I have worked extensively on platforms such as Outlier, Scale AI, Appen, and Remotasks, consistently delivering precise results and maintaining top-tier accuracy metrics across high-volume projects. My background also includes technical communication in Web3 and cybersecurity domains, enabling me to generate and evaluate AI training data in both general and highly technical contexts. I am reliable, adaptable, and thrive in remote, instruction-driven environments where accuracy and consistency are critical.
