Freelancer Overview

I have hands-on experience in AI training and data labeling through my work with Turing and Alignerr, where I evaluated and ranked LLM-generated responses, engineered prompts across medical and scientific domains, and annotated datasets for supervised fine-tuning using detailed rubrics. I applied RLHF methodologies, assessed chain-of-thought reasoning, flagged safety and policy violations, and delivered structured feedback that directly informed model improvement cycles. What sets me apart is my Doctor of Pharmacy background combined with a peer-reviewed publication, which gives me a strong edge in biomedical fact-checking and identifying hallucinations in health-related AI outputs — a high-demand niche in AI training. My quality assurance experience in a regulated pharmaceutical environment further sharpened my ability to follow complex guidelines with precision and consistency, exactly the standard these platforms require.
