Driving Core UX at Scale for 13+ Years

Senior UX/UI Designer
13 years · Web & Mobile

For more than a decade, I helped shape the UX of ImmoScout24 one of Europe’s leading real estate platforms. My work focused on simplifying complex decision-making journeys for millions of users every month, across web and native apps.

The platform supports highly complex user journeys from exploration and search to decision-making and long-term engagement across very diverse user needs.

My Role & Ownership

Over multiple years, I led the UX and UI of ImmoScout24’s most critical core products across mobile apps and web.

While I was responsible for the end-to-end UX/UI of the iOS and Android apps, my role extended far beyond mobile. I also shaped and continuously evolved key web experiences that define the platform’s first impression and core usage.

• UX and UI ownership of the native mobile apps (iOS & Android) over several years
• Long-term UX responsibility for search and discovery journeys across app and web
• Continuous improvement of search results, exposé pages and related detail views
• UX leadership for the homepage, shaping its structure, content logic and user flows over multiple years
• UX contribution to strategic initiatives such as AI-driven search and discovery on the homepage
• Close collaboration with Product Management, Engineering and UX Research to align user needs, business goals and technical constraints
