Freelancer Overview

I bring direct, professional experience in AI model evaluation and training data workflows from my role as an AI Model Evaluator for Microsoft Copilot. Over the past 18+ months, I have evaluated thousands of Copilot responses across 500+ enterprise user scenarios, systematically scoring outputs for accuracy, relevance, tone, safety, helpfulness, and factual correctness. I identify model weaknesses, hallucinations, and edge cases, then write detailed, structured feedback used to improve the model work that is directly equivalent to RLHF, data annotation, and preference labelling. What sets me apart is my rare combination of hands-on AI evaluation experience, deep technical domain expertise (Azure, AWS, Cybersecurity, Linux, M365), and native-level C2 English writing proficiency. This enables me to deliver high-quality annotations and evaluations on both general and complex technical prompts. I have consistently achieved 95% issue resolution rates and delivered measurable improvements (20% error reduction, 30% efficiency gains) through precise feedback and analysis. I am highly reliable in remote environments and ready to contribute immediately with the precision and quality that top AI training platforms demand.
