Rockstar🎓
Top SchoolDavid Pagan is a seasoned compiler engineer with over three decades of experience and six years in senior roles focused on C/C++ front ends and OpenMP at industry leaders including AMD and Intel. He specializes in compiler code generation and toolchain development, with notable open-source contributions to the high-profile LLVM project improving OpenMP codegen, allocator/align handling, and combined loop directives. Based in Redding, California, he blends deep low-level expertise from early work on PA-RISC and multimedia processors with modern compiler front-end development for clang. Comfortable in both sustaining and feature development contexts, he has a track record of shipping complex fixes across GCC and proprietary compilers while also building tooling for bug tracking and monitoring. His career shows a rare continuity across legacy and cutting-edge toolchains, making him a practical bridge between decades of compiler design and contemporary parallel programming models.
