About me
I turn ambitious ideas into products people genuinely love to use.
For over eight years I've partnered with startups and studios to design and build digital experiences — from first sketch to shipped code. My sweet spot is the overlap of design and engineering, where craft meets performance.
I care about typography, motion and the small details that make an interface feel alive. When I'm not pushing pixels, I'm exploring new tools and mentoring designers.
