I have worked for Apple since 2005, holding a number of different
positions over the years
(a partial history is available in the Apple section of my résumé). These days, I run the Developer
Tools department, which is responsible for Xcode and Instruments,
as well as compilers, debuggers, and related tools.
To answer a FAQ: Yes, I do still write code and most of it goes to llvm.org.
However, due to the nature of the work, I usually can't talk about it until a
couple of years after it happens. :)
I lead and am the original author of the LLVM
Compiler Infrastructure, an open source umbrella project that
includes all sorts of toolchain related technology: compilers, debuggers,
JIT systems, optimizers, static analysis systems, etc. I started both
LLVM and Clang and am still the individual with the most commits.
Of course, as the community has grown, my contribution is being dwarfed by those from a
wide range of really amazing folks.
LLVM has enjoyed broad industry success - being widely used in commercial
products - as well supporting hundreds of academic papers. For its
contribution to the software industry, LLVM has been recognized with the ACM Software System Award.

Here are some of my more notable publications from my graduate school work.
