Rockstar🎓
Top SchoolDan Sinclair is a Staff Software Developer with 17 years of experience specializing in graphics, shader toolchains, and build/CI engineering, currently based in Waterloo, Ontario. At Google he has driven correctness and compatibility across critical Khronos projects (glslang, SPIRV-Tools, SPIRV-Cross) and helped author the WGSL spec for WebGPU, bridging deep compiler knowledge with practical build and release automation. His open-source work ranges from low-level SPIR‑V validation and SPIR‑V generation to updating WGSL samples and maintaining cross-platform build systems, demonstrating both protocol-level rigor and hands-on delivery. Comfortable across C++ toolchains, Ruby servers, and build pipelines, he combines long-term technical stewardship with frequent contributions that reduce warning noise, fix uninitialized behaviors, and adapt projects to upstream changes. An uncommon strength is his ability to move between specification writing and nitty-gritty compiler validation, ensuring language docs and implementations evolve in lockstep.
