DevReach is international developer conference held in Sofia, Bulgaria. For two days the conference gathered more that 500 attendees from 15 countries. I polished the logo and created the main concept including all deliverables like badges, t-shirts, tote bags, agenda leaflet, signage, social media images. Programming is about math and logic, so I looked for an inspiration in the basic geometric shapes and created several backgrounds to convey that idea. Then I went further and designed custom letters for the tote bag and the t-shirts.
