Chris B
Principal Software Architect at Microsoft
Redmond, Washington, United States
Summary
🤩
RockstarChris B is a Principal Software Architect in Redmond with a decade of experience building cloud services and designing defensive cybersecurity architectures at Microsoft. He brings deep compiler and backend expertise—demonstrated by substantive contributions to high-profile open-source projects like LLVM/Clang and the DirectX Shader Compiler—where he implemented HLSL code generation, fixed UBSan issues, and improved driver and frontend behavior. Comfortable in both systems and service domains, he blends low-level compiler internals with practical cloud design to make performance and correctness trade-offs visible and manageable. Colleagues rely on him for refactoring tricky codepaths and untangling build and runtime issues, and he pairs hands-on engineering with a knack for clear architectural thinking that reduces operational risk.

Contributions summary:Chris contributed to the development of the DirectX Shader Compiler. Their work primarily involved implementing and improving code generation for HLSL, and also involved refactoring several code areas. Key contributions include adding helper methods for resource kinds, implementing bit shift behavior in the frontend, addressing and fixing a set of UBSan (Undefined Behavior Sanitizer) failures, and resolving an issue related to copy-in/copy-out parameter passing in shaders. Furthermore, the user implemented functionalities such as adding time report and various fixes for template issues.

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
Role in this project:Backend Developer
Backend DeveloperContributions:767 reviews, 136 PRs, 238 pushes in 5 years 6 months
Contributions summary:Chris primarily contributes to the HLSL (High-Level Shading Language) compiler project within the LLVM ecosystem. They are involved in implementing features related to HLSL's floating-point literal suffixes, handling preprocessor directives, and enhancing the usual arithmetic conversions for vector types. The user also works on improving the DXC (DirectX Shader Compiler) driver, specifically adding flags to enable metal shader conversion and addressing build processes. Their contributions include testing and code cleanup to improve the compiler's accuracy and functionality.
