Freelancer Overview

As an AI Data Trainer, I have hands-on experience generating, evaluating, and refining outputs across leading large language models including ChatGPT, Claude, and Gemini. My work centers on prompt engineering and prompt optimization, AI testing, and response evaluation—assessing model outputs for accuracy, relevance, and usability, and conducting careful research and fact-checking to ensure data quality. As an MBBS student, I bring strong analytical reasoning, attention to detail, and the disciplined documentation habits essential to producing reliable training data. What sets me apart is the combination of practical AI-assisted development and clear written communication. I built Legion Ledger, a data collation and organization project developed in VS Code with Claude, which demonstrates my ability to apply AI-assisted workflows to real information-management tasks. Alongside Python programming and a background in freelance writing, this lets me approach AI training work with both technical understanding and the precise, well-structured writing that high-quality labeling depends on.
