During 2015 when working part-time at Aalto University, I realized we had a need in our Master Program. Every year 60 students are divided in 10 to 11 teams to work in a year-long project. In one hand they have to create travel plans and several expenses claims. In the other hand, the Program staff has to process everything and manage the budget, in paper! (can you still use a pen?)
After recognizing and validating the need, I have created and tested with the students a few prototypes using Google Forms with a couple of scripts running on the background to provide some basic functionality. Then the next step was to put together my Ruby on Rails skills and create this app to make everyone's life easier. Now students can create all those claims online and administrators can manage everything on the other side.
The system is in beta release, so it will be tested throughout this year.
