Freelancer Overview

As an AI Training Specialist, I have a proven track record in optimizing and securing advanced language models through RLHF, Evals, and Safety projects. My expertise spans the end-to-end data lifecycle, including high-accuracy data and image labeling, transcription, and the rigorous evaluation of parameters to ensure linguistic coherence and cultural adaptation in both Spanish and English. I am highly proficient in writing and modifying complex prompts and performing strict fact-checking to verify the truthfulness and reliability of AI outputs. Notably, I have demonstrated leadership in high-stakes environments by supervising Red Teams, where I led efforts to stress-test models and identify vulnerabilities. My work focuses heavily on AI safety verification, utilizing my skills in rubric creation to audit and refine responses, ensuring they meet professional standards for safety, accuracy, and natural audio/prosodic delivery.
