Simon Geilfus
Design Technologist C Developer at Self-employed
Brussels, Belgium
Summary
👤
SeniorSimon Geilfus is a Brussels-based design technologist and C++ graphics programmer with 14 years of experience crafting interactive, immersive and creative tools for art and commercial projects. He blends low-level graphics expertise—contributing shader, FBO and depth-testing work to the widely-used open-source Cinder creative coding library—with a designer’s sensibility for spatial and experiential systems. As a long-time freelancer and former Design Technologist at Rare Volume, he builds everything from runtime-compiled C++ creative apps to content-creation and animation pipelines for VR, mobile and large-scale installations. His background includes teaching and artist residencies at institutions like La Cambre, Stanford-associated programs and Zero1, reflecting a practice that sits at the intersection of code, art and education. Notably, he often solves unconventional format challenges by authoring bespoke tools and extensions rather than relying on off-the-shelf software.
