Freelancer Overview

I am a medical doctor and AI training specialist with extensive experience in data labeling, annotation, and RLHF for leading platforms such as Telus International, Appen, Intron Health, and Welocalize. My background uniquely combines clinical expertise with advanced skills in natural language processing, semantic annotation, and medical fact-verification, particularly for healthcare and technical domains. I have consistently delivered high-quality, accurate data for training large language models, specializing in identifying subtle errors and hallucinations in AI outputs. In addition to text-based tasks, I have provided professional audio recordings and phonetic transcriptions for voice-AI training, ensuring high fidelity and linguistic nuance. My work is driven by a commitment to data quality, privacy compliance, and continuous optimization of AI systems.
