Freelancer Overview

With experience in copywriting, sales, and managing creative projects end-to-end, I bring a rare mix of language precision and results-driven thinking to my work. My sales background has sharpened my ability to understand intent and craft responses that land — whether for a client or an AI model learning to communicate better. I'm detail-oriented, comfortable with rubrics and feedback, and genuinely interested in the role human expertise plays in making AI more intelligent.
