Freelancer Overview

I have extensive experience training large language models (LLMs) in STEM-related tasks, especially in physics and mathematics. My work has involved writing and reviewing prompts, correcting model outputs, and designing adversarial examples to test reasoning and conceptual understanding. I’ve contributed to the development of LLMs by refining their logic, enhancing their mathematical clarity, and helping improve their ability to follow structured instructions. In addition, I’ve worked as a Quality Analyst, reviewing the work of other AI trainers to ensure consistency, clarity, and alignment with project guidelines. This role sharpened my attention to detail and strengthened my ability to give clear, actionable feedback. Combined with my experience teaching university-level physics and calculus, I bring a strong foundation in both pedagogy and technical evaluation, which allows me to create and assess high-quality content that helps AI systems better understand human reasoning.
