Driving core UX at scale for 14+ years.

The Scale

Millions of users. Many intents.

ImmoScout24 serves users with very different goals: renting, buying, investing, comparing neighborhoods, saving searches, returning to listings and making high-stakes housing decisions over time.

The UX challenge was rarely a single screen. It was the continuity between entry points, search behavior, result evaluation, detail pages and repeat usage across app and web.

Design Judgment

Design for continuity.

01

Own the ecosystem

Connect homepage, search, result list, exposé and app experiences so users do not have to relearn the product at every step.

02

Reduce decision friction

Make complex search and comparison tasks easier to scan, adjust and revisit in high-intent real estate journeys.

03

Scale patterns

Create reusable UX foundations that help teams move faster without fragmenting the marketplace experience.

Ownership

Core UX across app and web.

Over multiple years, I led UX and UI work on native iOS and Android experiences while also shaping key web surfaces such as search, homepage, result lists and exposé pages.

This work required close collaboration with product management, engineering, research and analytics, balancing short-term product goals with long-term usability and trust.

Sustained UX quality at marketplace scale.

User impact

Clearer search, discovery and evaluation journeys helped users move through complex real estate decisions with more confidence.

Product impact

Reusable UX patterns and shared product logic supported faster alignment across app, web and cross-functional teams.

Business impact

The work supported core marketplace engagement and created stronger surfaces for value-added services and long-term user relationships.

Learning

Scale rewards consistency.

At marketplace scale, UX maturity does not come from one redesign. It grows through repeated decisions that make the product easier to understand, easier to extend and easier to trust.

The most valuable work was often the least theatrical: improving patterns, reducing friction and protecting continuity across many teams, platforms and product moments.
