Hi Simon:

I'm happy to help with Buildbot, Travis CI, or whatever build system is preferred.

I have administered and curated the continuous integration environment at Verafin for several years. I have reasonable experience with a variety of operating systems and test systems.

I can't reasonably take lead on this, due to inexperience with GHC's test suite and Haskell testing in general.  I am happy to act in a support role: troubleshooting, debugging, and programming to get this back up and keep it solid.  I just need a mentor to point me at the right problems to solve.
