Hello friend.
I love open source. I am doing open source since I started professional software development in 2009. That is why I invest a lot of my free time in working on favorite projects of mine such as EventFahrplan, Umweltzone and Wo ist Markt?. Since April 2016 I am working part-time to have one unpaid day per week and weekends to maintain, manage and further develop these projects. Many other projects of mine or projects which I contribute to can be found in the repositories list of my GitHub profile.
I would like to keep my engagement up and running but as everyone I am constrained by the amount of free time and paying my bills. If you decide to sponsor me then you are supporting me as a person and so the projects which I decide to work on. Every sponsoring amount will help me to avoid doing contract work instead.
If you need any other information regarding my projects or the sponsoring please do not hesitate to contact me.
Thank you.
Cheers, Tobias
