We support the standard Haskell compilers and libraries. We can also extend, maintain and support other existing Open Source software.
Examples of previous work include several years of GHC support for Microsoft Research, and making a 64bit Windows port of GHC for the Industrial Haskell Group.
Ian has done a fantastic job of maintaining the GHC compiler for a large and demanding community of Haskell developers and compiler hackers. He is diligent and knowledgeable, and I trust his judgment.
