Munich, Germany Rendering Algorithm Engineer - Contract Employee June 2023 – Present 

• Improved rendering performance with efficient compute-shader-based software and hardware multi-view shadow rasterization, achieving a 3x boost in micropolygon rendering. 

• Optimized Micropolygon Rendering by implementing Two-Pass HZB Culling and Occluded Shadow Culling, resulting in a 70% reduction in draw calls. 

• Created an efficient multi-group GPU MPMC Task Queue for LOD Selection and HZB Culling of clusters, optimizing performance 

• Introduced Geometry Shader support to O3DE. 

• Developed Virtual Shadow Mapping for Micropolygon Rendering enabling caching of Directional Light Shadows. 

• Optimized Raytracing for Micropolygon-like rendering systems with custom acceleration structures. Masters Thesis Student August 2022 – April 2023 

• Introduced performant Micropolygon Cluster selection and frustum culling for multiple views. • Prepared a pipeline for cluster generation specifically for Skeletal meshes. 

• Introduced Deferred Rendering for O3DE and Vertex Shader based skinning for skeletal meshes 

• Migrated Micropolygon cluster selection from CPU to GPU compute shaders, resulting in a 10-fold reduction in processing time.
