Become a sponsor to Tilo Prütz

Hi, I'm Tilo Prütz and I'm into computers and programming since I was ten. This was back in the dark days of the down-going GDR (East-Germany) and I had the luck to get access to an Atari 800XL which was hot stuff for us back then.
Since then I developed software in many different languages on many different platforms for fun and to earn my living. I'm eager to work on open source software because I am happy that there is so much and useful of it out there.

Current Work

At the moment my favourite programming language is Go and the most time working on open source software I spent as a core developer on Fyne toolkit which is a really fyne ;) UI framework.
I contribute to a lot of open source projects. Mostly because I use them and provide bugfixes or feature enhancements.
Besides that I work on a MPD client including an HTTP audio stream player called TMPC.

Previous Work

Besides many of smaller contributions to many OSS projects to fix bugs or add nice-to-have features I worked on my own Objective-C foundation framework as cross-platform replacement of Apple's foundation.
I also invented my own unit testing framework TUnit for Objective-C because back then OCUnit was unusable (at least for me). It was first inspired by the JUnit framework and later got a lot of nice features inspired by RSpec.
