Summary
👤
Senior🎓
Top SchoolPeter Guttek is a Principal Software Engineer and computer graphics specialist with over 15 years of experience building real-time rendering, animation, and character pipelines for games and VFX. Based in Düsseldorf, he has driven graphics and animation systems at studios including GOALS, Ubisoft, Guerrilla Games and contributed performance and Vulkan expertise to the popular Dear ImGui project. His work spans low-level GPU optimization, deterministic shader math across IHVs, raymarched heightmap/SDF research, and practical toolchains that integrate Maya, UE5 and custom engines. He blends research-driven solutions (published work on modern OpenGL rendering) with production polish—optimizing shaders, compute node graphs and skinning/rigging pipelines. Known for finding subtle performance bottlenecks (e.g., frame-index issues in Vulkan backends) he also improves debuggability by enabling validation-layer workflows. Comfortable leading cross-discipline pipelines, he pairs deep graphics systems knowledge with hands-on engineering and tool development.

Dear ImGui: Bloat-free Graphical User interface for C++ with minimal dependencies
Role in this project:
Full-stack Developer
Full-stack DeveloperContributions:8 commits, 5 PRs, 20 comments in 1 year
Contributions summary:Peter primarily contributed to the Vulkan backend of the Dear ImGui library, focusing on improving its performance and stability. They fixed a performance bottleneck related to frame indexing, and enhanced the backend to optionally enable Vulkan validation layers for debugging purposes. The user also addressed several validation errors reported by the debug layers and improved the image presentation mechanism. These changes demonstrate expertise in Vulkan graphics API and integration within the Dear ImGui framework.
