I've been a free software developer and maintainer since the mid-1990s. I have contributed to dozens of projects, and I'm good at working effectively with new collaborators.

I maintain many programs in the area of text processing and editing, such as

• The spell-checking library Enchant
• The character set converter Recode
• The text printing utility GNU a2ps
• The lightweight Emacs clone GNU Zile
• The PDF utility pdfjam
• The PostScript utility psutils

I also contribute to many other projects such:

• GNU Emacs
• GNU autotools (automake, gnulib etc.)
• Racket (Scheme implementation and IDE)
• Vala (programming language)

I am a Debian Maintainer (that's a junior Debian Developer!), and I help package some of the programs I maintain for Debian.

I am also an accomplished technical writer and editor. Larger projects include proof-reading Mastering Ethereum and translating Elements of Automata Theory from French into English. I constantly improve free software source code comments, documentation and web sites, fixing typos, correcting technical errors, and improving clarity. I understand the problems non-native users of English typically have, and am adept both at writing clearly for non-native readers, and understanding what non-native writers mean, so as to reword it more comprehensibly.

Sponsorship enables me to spend more of my time on this work, particularly keeping uncool but tried-and-tested code working well, and improving tools for other free software developers.
