What I'm looking for

I'm looking to build game engines, graphics features, and cross-platform tools, drawing on my C++, rendering, plugin-development, and backend experience.

I'm contributing to RSX at InstaLOD/RSX, a new game engine positioned as a competitor to Unreal Engine and Unity. I integrate features such as billboards, fix OpenGL issues, and use RenderDoc for debugging.

My work also includes maintaining and extending plugins for Blender, Unity, Unreal Engine, Maya, 3DS Max, VRED, and soon Cinema 4D, using C++, Python, C#, MEL, and MAXScript.

During my Computer Science master's at KIT, I built a Minecraft-style game and a real-time ray tracer with C++ and Vulkan, implementing photorealistic lighting, physically based materials, compute shaders, and path-tracing algorithms.

I've also worked in backend development at CAS Software AG and quality assurance at IONOS. My master's thesis applied SAT solving to pack irregular objects on a grid, while my bachelor's thesis used C#, UWP, Bluetooth, Arduino devices, and data analysis to adapt vibration patterns in real time.
