open-source scientific software, devtools, mobile applications, ...
Below is a list of projects I am involved with (as a maintainer, member, core-developer, contributor). I do NOT maintain all of the projects listed below. In fact, I am not even a “collaborator” for some of the projects mentioned here, but all of these projects have some significant contributions from me. I also voluntarily supervise students for programs like Google Summer of Code.
