Freelancer Overview

I am an AI Trainer and LLM Evaluator with hands-on experience in data labeling, annotation, and quality assurance for large language models. I have evaluated and annotated outputs for correctness, reasoning quality, and instruction adherence, applying scoring rubrics and providing written justifications to ensure high-quality training data. My work includes comparative assessments, edge-case analysis, and bias detection, supporting supervised fine-tuning and reinforcement learning from human feedback (RLHF). With a strong background in machine learning, data science, and structured evaluation, I bring precision, attention to detail, and reliability to every task. I have consistently maintained high QA standards, achieving perfect evaluation scores in recent projects. My expertise spans text, document, and structured data annotation, and I am committed to producing accurate, consistent, and ethically sound AI training datasets.
