About me

Hi, I'm Matic, a UX/UI designer and front-end developer with over 20 years of experience designing and building digital products.

I specialize in solving complex product challenges, designing scalable systems, and creating intuitive user experiences that work across teams, platforms, and technologies.

In 2007, I published a 250-page book on web design and development, becoming the youngest Slovenian author of professional literature in the field. I later earned an Engineer’s Degree in Multimedia Studies from the Institute and Academy of Multimedia.

Over the years I’ve worked with companies across Europe on products ranging from enterprise SaaS platforms to high-traffic systems.

I enjoy working at the intersection of design, technology, and problem solving - collaborating with teams to turn complex ideas into clear, reliable digital experiences.
