Here is an excerpt including some of my projects.
Public Transport Nicaragua
With help of several tools we were able to build the first trip planning application in Nicaragua.
Funded by Open Technology Fund the F-Droid project had the possibility to hire some developers to work on different tools. Together with other developers and designers all around the world I had the opportunity to help on creating Repomaker, a web application to easify the creation of own F-Droid app stores.
LegionBoard was a free and open source changes management system for schools.
