About
A design-minded developer who sweats the details.
I'm Marc, a frontend developer in Stockholm with a foundation in full-stack development. I work mostly with Next.js, React, TypeScript and Tailwind, and care as much about how something feels as how it's built.
I've built websites and e-commerce for startups and small businesses, and worked with brands like Folkspel, Vattenfall and Nova 8 during my time at Digital Fans — collaborating closely with designers, backend developers and business teams.
Right now I'm going deeper into performance, accessibility and design systems, and exploring Flutter & Dart for mobile.
