Rockstar🎓
Top SchoolRobert Gerdisch is a Senior Software Engineer with 12 years of experience building high-performance graphics, mixed reality, and immersive ML systems at Microsoft from low-level DirectX raytracing to WebXR and native XR runtimes. He blends front-end UI craftsmanship in Babylon.js with C++/OpenXR and native platform work on BabylonNative and DirectX samples, helping bring Unity MRTK shaders and single-pass multi-view rendering to Web and HoloLens with a focus on 60fps performance. His portfolio spans museum-grade AR/VR installations—designing continuous, artist-driven simulations and mobile AR experiences—and production engineering for SteamVR and HoloLens integrations. An active open-source contributor, he’s improved real-time rendering materials, WebXR ergonomics, and raytracing performance in prominent repos like Babylon.js and DirectX-Graphics-Samples. Based in Zurich and trained at Yale in Computer Science and French, he combines deep graphics systems expertise with a knack for making technically ambitious interactive experiences feel polished and reliable. Notably, he has a track record of shipping both creative, long-running simulations for exhibitions and hard real-time engine improvements that translate directly into smoother, more immersive user experiences.
