Freelancer Overview

I specialize in AI Red Teaming and Conversational Auditing, where I rigorously test and interrogate AI systems to identify logical flaws, hallucinations, and inconsistencies. My experience includes stress-testing AI agents, correcting fabricated information, and ensuring persona and tone alignment with brand guidelines, which directly contributes to high-quality training data and annotation standards. Leveraging my advanced pattern recognition skills and neurodivergent hyper-focus, I excel at detecting subtle errors that may be missed by others. I am proficient in data analysis, documentation, and compliance, and have a strong background in business operations and global communication. My work ensures that AI models are safe, accurate, and aligned with both ethical and operational requirements.
