Freelancer Overview

I have experience in AI training data and data labeling through roles at Mercor and DataAnnotation Tech, where I supported large language model improvement through prompt writing, rubric design, response evaluation, ranking, and quality review. My work has included both text-based and multimodal tasks, with a strong focus on clarity, accuracy, instruction-following, and research-based reasoning. What sets me apart is my experience moving beyond task completion into quality-focused responsibilities, including reviewer work, contributor feedback, onboarding support, and maintaining strong performance in fast-changing project environments. I combine hands-on AI training experience with a Bachelor of Science in Marketing from The University of Texas at Dallas, which strengthens my ability to produce human-aligned, well-structured, and analytically sound training data.
