CTO @ ARK.io. Making things happen in the blockchain world, by bringing blockchain technology to the masses.

I mainly participated in large industry projects in various roles. After finishing B.Sc. in computer science I was working for the largest energy company in Slovenia – Petrol d.d., where I was managing successful large ICT projects for mobile fuel solutions. After four years in industry I was invited to work at the University of Maribor, where I also started my Ph.D. – in the area of human computer interaction (ongoing). During my work at University I always loved being actively involved with the industry. My main role was knowledge transfer, project management and consulting on various successful projects. I received a recognition for exemplary achievements at University of Maribor and finished Sprout Entrepreneurship course led by TakingITGlobal and received a certificate of completion for Social Entrepreneur. My experience was gained in various roles from strategic planning, setting goals and KPI, budgeting, negotiating as well as entire product life cycle management.
