Open source software development

I have been a contributor to open-source projects, mostly Haskell:
xmobar, cabal-install, darcs, string-conv, TagSoup.

I created and maintain many open-source projects including:
py-mkvenv, epub-tools, epub-metadata, hsinstall, uacpid, hscrtmpl, photoname.
Over 50K lines of original code in Haskell alone.
These projects are hosted and documented in detail on github.

I run the Haskell Meetup in downtown Raleigh, NC.

I am experienced in epub creation and maintain the epub edition of
“(Nothing But) Flowers” by John G. McDaid, a Creative Commons
licensed work of fiction.
