Freelancer Overview

I am an experienced AI Trainer, Data labeling especialist and Subject Matter Expert in Maths, English, Hindi, and Physics with over five years dedicated to data annotation, response evaluation, and dataset refinement for AI model training, particularly in Mathematics, Physics, and multilingual (English-Hindi) domains. My work spans AI-generated content evaluation, logical reasoning validation, hallucination detection, and step-by-step solution assessment for large language models and chatbots. I have contributed to projects like Cypher Evals C, Diamond, and Ruby, focusing on response ranking, dataset calibration, and multilingual content quality. My technical toolkit includes LaTeX for mathematical formatting, advanced MS Office, and structured rubric-based evaluation. I excel at identifying logical errors, ensuring data accuracy, and providing actionable feedback to optimize AI performance across academic and conversational datasets.
