I maintain numerous open-source projects on GitHub. This page gives you an overview what I have been working on. Most of these projects are WordPress-related as well, for example libraries I use to speed up my workflow, tools or simply upcoming plugins that I haven’t pushed to wordpress.org (yet).
Feel free to check anything out – several of these projects don’t really have any documentation since I use them internally, but I’m willing to help out if anything strikes you as particularly useful for your own cause. Maybe you even wanna help contributing which I’d absolutely appreciate!
