## 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.  
These projects are hosted and documented in detail on [github][gh].

I run the Haskell Meetup in downtown Raleigh, NC.

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