About me

I'm a frontend developer from Greece who cares about the parts that make products fast: CSS architecture, design tokens and build tooling. I've shipped an SCSS framework on npm (Zeus CSS), a Chrome DevTools extension, Figma plugins and a handful of games — and I write about all of it on FrontDose.
