Freelancer Overview

I’m an AI output grader and data labeling specialist with a strong background in mechanical and electrical engineering. Over the past two years, I’ve contributed to LLM evaluation projects for leading AI clients, applying detailed rubrics to assess model performance in accuracy, safety, tone, and factuality. My 20+ years of precision work as a technical translator (mechanical, energy, and IT domains) have given me an exceptional eye for consistency and technical clarity. I bring both engineering expertise and linguistic rigor to data labeling, annotation, and prompt evaluation—helping improve the quality and reliability of AI systems.
