## Open source software development

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

I created and maintain many open-source projects including: 
[py-mkvenv][pmsrc], epub-tools, epub-metadata, hsinstall, uacpid,
hscrtmpl, photoname. 
Over 50K lines of original code in Haskell alone, representing nearly 20 years
of deep experience with the language. 
These projects are hosted and documented in detail on [github][gh].

I run the Haskell Meetup in downtown Raleigh, NC, USA.

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