Labeling Experience

AI Training Specialist (RLHF & Evaluation)

RLHF

As an AI Training Specialist, I validated Large Language Models (LLMs) by conducting technical audits focused on code integrity and mathematical logic. My role involved evaluating and providing feedback on complex reasoning and the scientific accuracy of AI outputs in English, Portuguese, and Spanish. I ensured the logical rigor and alignment of language model responses according to RLHF workflows. • Performed auditing and validation on code and technical reasoning outputs. • Evaluated LLM responses for mathematical and logical soundness. • Provided specific feedback across multiple languages for LLM fine-tuning. • Specialized in technical problem-solving and scientific integrity for model optimization.
