Summary
🤩
RockstarHans-Kristian Arntzen is a software engineer and founder of Arntzen Software AS with a decade of hands-on experience in graphics and low-level systems development. Based in Trondheim, Norway, he contributes to prominent Khronos projects—SPIRV-Cross, Vulkan-Samples, and Vulkan Validation Layers—focusing on shader compilation, Metal backend code generation, 16-bit arithmetic performance, and robust validation logic. His work blends practical tooling (disassembling SPIR-V to high-level languages) with performance-minded sample implementations and careful correctness fixes in validation code. Colleagues know him for improving obscure but critical areas like shader record buffers, multi-patch modes, and image usage tracking that materially reduce bugs and platform gaps. He brings an engineer-founder mindset: shipping production-quality C/C++ contributions while running a small software company.
