Yettel is one of the biggest telecommunication companies of Bulgaria and main client of guts&brainsDDB, the agency I worked for, part of the DDB Worldwide group. We offered to Yettel to develop an app focused on the 100 tourist sites of Bulgaria and digitalize the physical passport, where you collect stamps from the sites and turned into a digital one, creating signs with QR codes all over the sites in Bulgaria. We worked on this project for about a year and we made a beautiful app, working with over 30 different illustrators. I was responsible for creating lots of digital and print materials about the campaign, alongside the UI design of the application. The campaign won lots of prestigious awards in Bulgaria and Europe. https://www.yettel.bg/uslugi/za-teb/100obekta https://www.youtube.com/watch?v=L6xQsTU1U7s
