One of the biggest(.) Google projects with Haskell is probably Ganeti ( https://github.com/ganeti/ganeti ), which is a mix of python and Haskell and has been around since 2008ish (although Haskell was introduced later, iirc).

We recently moved our main development to github so the repo seems a bit empty, we're certainly happy to get more contributors if you are interested, as the community is fairly small and specialized. Everyone is welcome.

Source: I'm one of the current main developers of the project.

(.) Note: I actually have no idea if it's the 'biggest'.

I helped out a bit with the BCL pretty-printer in my day. (Mostly contributed in-depth code reviews.)

Is Ganeti related to Ganpati? Sorry, it's been a bit since I left Google. Memory is fading.

Not at all, only the name is very similar :)

I just learned that we have a GUTS at my new employer, Bloomberg, too. But it has nothing to do with asking for a monorail between the Sydney offices.

There are only so many words. And many of them similar.

Lol at stating a fact and then citing thst you have no idea. Haha

Lol at the citation being the emoji of an anus, where he likely pulled the factoid from.
