About me

I'm a full stack designer with over 19 years of experience bringing ideas to life, from the first sketch to the finished product. Think of me as a one-man design agency: I handle everything from brand identity and UX/UI design to front-end development and user research.

I work hands-on rather than by handing a spec over. I'm equally comfortable in Figma and Adobe Creative Suite, writing HTML and CSS, or using AI tools to take the repetitive work off my plate.

I especially enjoy working with small businesses and startups, where one designer can still move the needle. The work changes shape from one month to the next, which is the part I like.

There are designers who only draw logos and designers who only design applications, and at that one thing they are better than I am. What is rare is the whole span: knowing what CMYK is and how to send a file to print so it comes back right, building an identity from nothing, running the research and the interviews, taking the findings to a board, testing a product and then designing it, and building the front end myself when a project calls for it. I work as a craftsman across all of it rather than a specialist in any one part, which is why leading a team suits me. I have done every job in the room.

While I can build simple sites myself, I know when to bring in the right expertise. For larger projects, I collaborate with Jakub from surfidea.dev, a full-stack developer who helps turn ambitious ideas into products that hold up once real people use them.

After work I'm a happy father of three. Owner of three bikes and one pair of rollerblades. Inspired by the timeless designs of legends like Dieter Rams. Watch geek. Big fan of new technology with interest in studying human perception.
