I'm "TomMD". To say I 'maintain' things might be an overstatement, but I've released a number of Haskell packages and minor fixes. Much of that was on my own but a significant portion were from my Galois days. I've had a few publications and am hoping to get to ICFP Seattle this year. Also years ago I made (cofounded) a company (Muse Dev) with Haskell as central part of the stack which was enjoyable.
Currently? Life is very busy so I'm just enjoying my Haskell time writing this and that rather than building much for release.
