DevReach is an international developer conference held in Sofia, Bulgaria. 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 inspiration in the basic geometric shapes to convey that idea. Custom letters were created for the tote bag and the t-shirts. Also, an additional batch of t-shirts was designed for a social cause.
