Finally, I launched my personal project, WePassengers.
This was created and designed just for the pleasure of building something.
I'm a UI designer, but I also wanted to try myself developing both the front-end and back-end parts.
Right now it's an open beta project, so you can request an invite and take a look at it.
Needless to say that feedbacks, suggestions and comments are really appreciated from all Dribbblers.
