Contemporary German history doesn't compress into a single narrative — it spans decades, ideologies, and lived experiences that resist a uniform visual language. The technical problem was building an interactive installation system in Qt that could deliver a coherent visitor experience across thematically heterogeneous exhibition units, at scale, inside a physical space that didn't exist yet during development

Architected a Qt-based application framework designed from the ground up to be modular — each installation unit could carry its own content, interaction logic, and visual identity, while sharing a common underlying system. Building and validating the experience ahead of the physical space meant defining clear hardware contracts early and stress-testing interactions in simulation. The result ships permanently at Haus der Geschichte Bonn, part of an exhibition spanning over 3,800 objects and seven decades of German history.
