Value Proposition

A designer who delivers code. My key differentiator is not just designing rigorous visual systems or mastering accessibility, but bridging the gap between design and development myself. I deliver production-ready Figma + SASS/Bootstrap code, reducing review cycles and implementation errors. With AI as a co-pilot, I scale creative production without sacrificing quality or design standards.
