Rockstar

Ross Nordby is a seasoned C# systems engineer with 11 years of experience focused on real-time physics and tooling for game development. Based in Chicago, he is a principal contributor to the BEPUphysics libraries (including bepuphysics2), where he has driven solver improvements, stability fixes, and performance optimizations that power 3D simulation demos and game systems. He builds backend components and developer-facing tools that help other engineers ship games faster, and his work shows a pragmatic attention to numerical robustness and resource management. Active in open-source communities (porby on LessWrong), he pairs deep low-level expertise with a mission-driven sensibility—he jokes about preserving humanity so people can keep playing games, but his code seriously improves the play experience.
