Reid Kleckner got into compilers at university, and eventually landed a job at Google working on Clang for Windows. This project required a full tour of duty of the compiler: frontend changes, new IR constructs, low-level calling convention changes, and new debug info formats. Reid went on to lead a team at Google responsible for maintaining the server production C++, where he worked on addressing build scalability problems, notably relocation overflows from 2+GiB text sections among other things. His latest role is at NVIDIA, also working on continuous integration of LLVM.
