About Fiona Z.

I build modern digital products where design and engineering actually meet. I can take a flow from messy idea to clean UX, design it in Figma, and ship it in production with React and TypeScript.I have 10+ years across agency and in-house teams, including fast-paced product launches, design system work, and day-to-day collaboration with designers, PMs, and engineers. I care about craft, but I care even more about delivery, consistency, accessibility, and building systems that help teams move faster without breaking quality.Right now I lead design and frontend execution as a Senior Designer and Developer and Team Lead at Full Glass Wine. Previously, I was a Senior Developer at Work & Co, and before that I built high-traffic experiences at BuzzFeed and started out at Thoughtworks in a hybrid design and development role.If you need someone who can own the UI from concept to code, build scalable systems, and ship polished work, let’s talk.
