Thinking code and design together
Even in the design phase I know how something can be built. That saves rounds of feedback and surprises during implementation.
About me
Code and design. For over 20 years.
I’m Karsten, a web designer and frontend developer in Berlin. I studied communication design and have been building websites for over 20 years: two decades at STRATO, and always for my own clients on the side. Since 2025 I do this full time.
I design and code myself. That is why nothing gets lost between design and implementation.

Way of working
How I work
Accessibility from the start
I plan for WCAG and the German accessibility act (BFSG) from the first draft. Fixing it afterwards is more expensive and rarely complete.
Systems instead of single pages
Reusable components and a living style guide keep websites maintainable for years.
Tools
What I work with
Daily
- HTML5
- CSS3 / SCSS

Right now I am deepening my backend skills (Node.js, SQL, auth) in a further training at neue fische, so that I can build projects from the interface down to the database myself. The first round produced Berlin Street View, a web app for Berlin street art built with Next.js and TypeScript. View Berlin Street View
