Over the years, I have been using innumerable open source projects, and I am thankful to all the people who worked on these. One of the best things of open source is that it is so easy to give back—so that’s what I did, and still do. This page provides an overview of my contributions to various open source projects, most of which in the WordPress universe.
The following list contains projects that I created myself and that are therefore contributions to open source in and of themselves:
