Freelancer Overview

I am an entry-level specialist focused on AI training, data labeling, and large language model evaluation, with hands-on experience comparing and annotating AI-generated text in both Spanish and English. My background in UX/UI design and project management has strengthened my structured thinking, attention to detail, and ability to follow complex guidelines. I have practiced evaluating model outputs for clarity, usefulness, and adherence to instructions, consistently documenting my decisions and identifying areas for improvement such as generic phrasing or repetition. With foundational training in RLHF and a commitment to providing high-quality human feedback, I am eager to contribute to data annotation and AI evaluation projects that require careful analysis and reliable, guideline-driven assessments.
