I'm a chartered mathematician, computer programmer, writer and book production editor. I have a number of packages on CTAN, and I write LaTeX books, illustrated children's books and crime & SF. I have a FAQ, a bug tracker and a feature request tracker for my LaTeX packages and a list of LaTeX resources. You can also find me on GoodReads.
If you're wondering about my avatar, it's the head piece of my hippochette.
