Freelancer Overview

I’m a bilingual AI Data Specialist from Brazil with experience in Reinforcement Learning from Human Feedback (RLHF), LLM evaluation, and data annotation. I have contributed to projects involving code review, text generation, and model response analysis, ensuring accuracy, clarity, and alignment with human intent. With a background in software development (Python, C#, JavaScript), I bring a technical understanding of model behavior and data quality assurance. I’m fluent in both English and Brazilian Portuguese, enabling me to handle multilingual labeling tasks and localization projects with precision.
