Designing things on the internet since 2004

Product designer and a psychologist, striving to evoke joy, comfort, and confidence by making the complex feel simple.

I started designing things on the internet some 16-17 years ago. Over the years I had the privilege to meet people from all over the world and work with them on projects in various industries.

I design to help people do their job with a sense of calm. I try to anticipate their struggle, identify the right problems, and solve them well. My goal is to design a "home", not a "house".

My email is stjepan@hey.com if you want to have a chat — I am always interested in meeting new people.

Up close & personal

About me
  • I prefer to think things through instead of moving fast and breaking things.
  • Working on stuff I've never done gets me excited. I love to figure things out as I go.
  • When picking a path, I tend to go for the one less traveled.
  • I ❤️ remote work.
  • Croatia native, I now live in the Netherlands with my family.
Here to help
  • I design products people don't struggle with.
  • Comfortable providing an outside perspective as a consultant or working from the inside as an employee.
  • Seeking to understand the broad context of product development (business goals, customer needs, and technical constraints) and focus on finding balance and harmony.
  • I code my designs to HTML & CSS and use JavaScript, PHP & SQL to spin up detailed product prototypes.
  • I used to run A/B tests back in the day when I was working on websites.
  • I've constructed questionnaires, conducted quantitative research, analyzed data, and almost went down the route of academic research.
