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:

genai-lib, py-mkvenv, 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 and more are hosted and documented in detail on github and codeberg.

From 2019 to 2024 I ran the Haskell Meetup in downtown Raleigh, NC, USA.

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.
