Rockstar🎓
Top SchoolJan Krassnigg is a software developer with 8+ years of experience designing high-performance C++ systems and building robust infrastructure for game engines and cloud services. He excels at architecture and large-scale refactors that produce safe, efficient, and easy-to-use APIs, with a strong emphasis on documentation and automated testing. A game-programming background gives him deep practical knowledge of CPU/GPU and memory behavior, which he applies to low-overhead designs and build-system integration. He has managed teams of up to 15 people, removing blockers and coordinating across art, gameplay, and platform teams while still contributing hands-on code. At Microsoft he worked on Azure Remote Rendering infrastructure and public docs, and he continues to contribute to the open-source ezEngine project, focusing on third-party library integration and build reliability. Based in Unterhausen, Germany, he prefers tackling the tedious but impactful engineering work—like build systems and documentation—that makes teams far more productive.
