Education

I hold no relevant higher education qualifications relating to the areas of Computer Science or programming. I feel more than comfortable in the company of intellectuals and I do have years of real-world experience under my belt building a wide range of technical solutions giving me a great insight into the digital product development process.

Here is what higher education i attended and how far i reached:

  • High Technical School of Professional Studies, Novi Sad, Serbia
    Course: Information Technologies

    I was working while studied here. After second kid and new job, i paused on third year, with couple of exams left.

  • Faculty of Technical Sciences, Novi Sad, Serbia
    Course: Computer Science

    I haven’t found here a good advance in programming and information technologies, as the program was pretty old and outdated. So i officially dropped out in 2005, when i decided to go full-time freelancing and learning on my own.

  • High School Education
    Technical School "Nikola Tesla”, Kostolac, Serbia, September 1999 - July 2003
