Summary
🤩
Rockstar🎓
Top SchoolMichal Ziulek is a Core Systems Engineer with 11 years of experience specializing in performance-oriented programming, low-level graphics, and systems optimization. He has shipped engine and driver-level work at Intel, DICE, and AMD, and now combines R&D for red-team tooling with independent game-engine and Zig ecosystem development. Proficient in C/C++, x86_64 assembly, Zig and DirectX 12, he contributes notable low-level improvements to open-source graphics libraries and a Zig game engine—adding projection math, SSE2 optimizations, and robust GPU resource handling. Based in Gdańsk, he pairs practical production experience with experimental projects (including a custom adversary simulation toolkit and game prototypes), reflecting a rare blend of graphics systems expertise and hands-on security tooling.

Role in this project:Backend Developer
Backend DeveloperContributions:1 review, 11 commits, 11 PRs in 4 months
Contributions summary:Michal primarily contributed to the `gpu` module of the Zig game engine, focusing on the low-level graphics API integration. Their work involved modifying and adding helper functions to structures like `VertexBufferLayout`, `RenderPipeline`, and `BindGroupLayout`. The user also made changes related to default values for structs and handling dynamic offsets, streamlining how graphics resources are managed within the engine. This suggests a focus on optimizing the rendering pipeline and associated resource management.
