Designing For Complex UIs In 2025

Roll up your sleeves — it’s time to brush up your UX skills! How would you architect an effective multi-level navigation for a large government website? What about enterprise-grade tables with intricate forms, filters and search? Or perhaps an accessible data visualisation and charts for a complex medical data set? Well, fasten your seat belt!

In this workshop with Vitaly Friedman, the UX lead with the European Parliament and Smashing Magazine, you’ll learn how to deal with real-life UX challenges from the ground up. Get ready: you’ll sail uncharted waters, design truly complex interfaces and receive feedback from people around the world. Plus: you’ll get a UX certificate for all your hard work as well.
