In short

About Me

I was born in Banja Luka, Bosnia & Herzegovina. Grew up constantly moving, exploring and trying new things. Karate was one of the first. Seven years of discipline, hard work and quite a few gold medals in international kumite championships. Then came breakdancing. I was hooked. Between 2008 and 2013 I hitchhiked over 12,000 kilometres across Europe, just to get to competitions and learn from people who inspired me.

That mix of structure and chaos (karate and breakdance) shaped the way I think and work. Focused and disciplined but flexible. Intentional, but not afraid to take creative risks.

In 2014, I moved to Zagreb, Croatia. These days I'm more of a family guy than a backpacking dancer. I split my energy between building smart digital products, going to the gym, hanging out in nature and occasionally losing to my kids in Beat Saber. It's a different kind of balance, but it works.

That mindset followed me into my work. Designing national ID systems, fintech tools, sport apps, or even e-commerce platforms. Over the years, I have designed for web, mobile (iOS, Android, Jio, KaiOS), wearables, custom Linux systems and gaming consoles.

What I do

Expertise

Product Design

End-to-end design of complex products: digital identity, payments, e-commerce and live sports data, on web, mobile, wearables and custom platforms. I take a product from research to launch and stay with it until it works for the people using it.

My work is used by millions of people across many countries and languages.

Design Leadership

I lead design teams and work as the design voice next to product, engineering and business leadership, including regulated products where legal and compliance sit at the same table.

I own the design direction, the priorities and the trade-offs, and I write decisions down so teams can move quickly.

Team Development

I build the conditions for designers to do their best work: clear standards, honest feedback and ownership of real problems.

I also mentor designers and product leads one to one and run workshops on UX, accessibility and product thinking. More than 23,000 designers have taken my accessibility course.

Product Strategy

I connect research, product and business goals into one direction. Before anything is designed, I make sure the team knows who it's for, what problem it solves and how we'll know it worked.

It keeps teams building the right thing, and it gives leadership a clear reason to commit.

Setting up how your team makes and writes down design decisions
Planning research that answers the question you actually have
A second opinion before a big product call
Mentoring and Workshops

For designers and product teams who want to grow, from a first lead role to running a whole team.

Typical focus areas
