Senior🎓
Top SchoolReza Saputra is a graphics-focused software engineer with 11 years of hands-on experience building high-performance rendering systems and games, currently contributing to HorizonOS graphics and VR compositor testing at Meta. He holds a PhD from the University of Waterloo in 2D computer graphics and has a track record of research-to-product work, including award-winning procedural mosaic algorithms and a related US patent. Reza's personal projects (reza.graphics, GitHub: azer89) demonstrate deep low-level expertise in Vulkan, DirectX12 and C++—from hardware-accelerated path tracing and bindless rendering to compute-driven frustum culling that handles 10,000 AABBs in under 0.025 ms. He also brings practical Unity/C# experience shipping mobile titles, optimizing draw calls and implementing ECS-based multiplayer systems. Comfortable across research, engine-level code, and tooling, he leverages profiling, automated testing, and even LLMs to drive reliable rendering performance on constrained devices.
