Freelancer Overview

I have experience supporting AI training and evaluation through high-quality data labeling, prompt analysis, and response evaluation for large language models. My work focuses on assessing model outputs for accuracy, reasoning quality, instruction adherence, and tone, as well as refining prompts to improve consistency and performance. I am comfortable working with complex guidelines, edge cases, and iterative feedback cycles to ensure reliable, production-ready training data.
