He is currently leading the front-end team at AVA, a Berlin-based company, where he is working on a platform that combines big data, pattern recognition and artificial intelligence to take the safety of individuals, organizations, cities, and countries to a whole new level. His main role is to create a contextual analysis of the processed data through a web-based client application. Marko is a long time member of DAFED, a non-profit organization that is working on networking and educating the IT community in the region.
