Senior🎓
Top SchoolRobert Rouhani is a Lead Programmer with 14 years of experience building high-performance game tech and shipping AAA titles like NBA 2K, LEGO 2K Drive and Fortnite features. He leads cross-discipline teams to solve CPU/GPU/memory bottlenecks, extending Unreal Engine with custom renderers, compute shaders, and platform-specific optimizations to hit tight framerate targets. A former CTO and Y Combinator Fellow, he pairs systems-level engineering (ARM NEON, SSE, RHI, shader uniforms) with product-minded leadership across consoles, PC, mobile and VR. An active open-source contributor, he has optimized core math and input functionality in the popular OpenTK library, reflecting deep low-level expertise beyond game features. Based in New York, he thrives on turning research prototypes and tooling into robust, production-ready systems under aggressive deadlines.

The Open Toolkit library is a fast, low-level C# wrapper for OpenGL, OpenAL & OpenCL. It also includes windowing, mouse, keyboard and joystick input and a robust and fast math library, giving you everything you need to write your own renderer or game engine. OpenTK can be used standalone or inside a GUI on Windows, Linux, Mac.
