Freelancer Overview

I have experience in AI training through remote roles, including working as a **Toloka AI Agent Assistant**, where I was trained to vet the work of AI agents, identify mistakes, and correct their outputs to make them more accurate, relevant, and useful. In this role, I was encouraged to use multiple AI tools to cross-check information and improve accuracy, while still applying my own judgment to ensure the final response met the required standard. I also worked as an **AI Data Contributor** with an India-based company, where I held live conversations to help train AI systems to better understand human communication patterns and respond more naturally. Beyond formal roles, I have also used **ChatGPT, Gemini, and other AI tools extensively** for both academic and non-academic purposes. This has helped me understand how AI responds, where it commonly makes mistakes, and how to guide it toward clearer, more accurate, and more useful outputs. My attention to detail, medical training, tutoring experience, and strong communication skills make me well-suited for AI training and evaluation work.
