Freelancer Overview

I am an experienced LLM evaluator, prompt designer, and AI data quality specialist with a strong background in computer systems and technologies. My expertise lies in evaluating large language model outputs for accuracy, reasoning depth, safety, and strict instruction adherence. I excel at designing and refining prompts to test edge cases, reduce ambiguity, and improve model determinism. My work involves providing precise, structured feedback, identifying errors or policy risks, and supporting multi-level classification and labeling tasks. I am known for my analytical approach, consistency, and high-quality written communication in guideline-driven environments. With hands-on experience in both evaluation and prompt engineering, I am passionate about enhancing AI systems through rigorous data annotation and quality assurance practices.
