I cannot talk about whole Balkans, but for Croatia only. Id say its noy difficult to find a job here in IT, especially if youre good. Average IT salaries are about double compared to contry average salary. Foreign companies have their IT centers here too, like Siemens, Ericsson, etc. So I'd say there is a deficit of IT workers here just like in most other EU countries. I think your only problem might be a working permit if you're from BiH. Since you're not a EU member yet Im pretty sure you can not get it easily.
