I am contributing to several open-source projects on GitHub. Many of them are WordPress plugins, but this page gives you an overview of all the other projects that I have been working on.

Torro Forms is an extendable WordPress form builder with Drag & Drop functionality, chart evaluation and more – with WordPress look and feel.
Custom metrics to use with WebPageTest agents
I have also developed numerous (more or less maintained) open-source projects of my own. Many of these projects are still WordPress-related, for example libraries I use to speed up my workflow, tools or simply upcoming plugins that I haven’t pushed to wordpress.org (yet).
Several of the 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!
