I designed a new system for AGH University of Science and Technology called "Exchange Student Registration System". It's main purpose is to serve Erasmus and other exchange students to sign for courses and create their academic profile.
The signing process (called "learning agreement") proposed by AGH was very complicated and involved many actors along the way. From students' perspective they were involved in one path, while AGH administrators and moderators seen the process as many different elements.
I ended up creating almost 90 designs of system views and its interactions. Everything is based on simple grid: bigger column with main content, navigation sidebar, action sidebar and adjustable main menu. This way user experience is similar everywhere.
