Simplifying Complexity
With Clear Design

Hi. I'm Grzegorz. I'm a Product Designer who turns complex problems into simple solutions. Over the years, I've helped companies like Timebook, eSky, and Appjobs create user-friendly digital products and led design teams that make both users and developers happy.

Based in Gliwice, Poland, I craft digital experiences by day, and spend my free time listening to podcasts, brewing coffee, taking photos, and tending to my garden.

I believe in making technology less complicated and more human. I focus on creating experiences that just make sense.

Design Strategy & Leadership

I help organizations establish effective design processes and build high-performing teams. Drawing from my experience leading multiple design teams, I create frameworks for success, mentor designers, and ensure design solutions align with business objectives while maintaining user-centered approaches.

End-to-End Product Design

I guide digital products through the entire design process, from initial concept to final implementation. Using an iterative approach of research, prototyping, and testing, I create solutions that engage users while driving business growth. My focus is on building products that are both purposeful and delightful to use.

User Research & Testing

I drive design decisions through systematic user research and testing methods. By implementing structured research programs, usability testing sessions, and design workshops, I help teams validate their assumptions and create products based on real user insights rather than speculation.

Design System Development

I create and implement scalable design systems that unite teams and ensure product consistency. By establishing shared components, patterns, and guidelines, I help organizations work more efficiently while maintaining design quality across all touchpoints. These systems serve as the foundation for successful digital products.
