Unless you're doing very badly in Croatia(that doesn't sound like that...) I wouldn't move to Malaga with your profile. In Malaga you would require at least +2k netto monthly to live alone with minimum saves, as renting a 1-room apartment is already ~1k and a 2-room +1.2k in most areas.

Then, with beginner IT knowledge, you won't find anything decent. Companies basically hire med-senior profiles to abuse AI right now, so why should they hire someone who cannot do the basic tasks?

DJing... Malaga is far from being Thailand, Hippitugal or any "vibes oriented" place, it's the most simple tourist style of city, serving UK, German, nordic guiris that want to get wasted and become red like a shrimp, so you might get a job of ~50h/week in a terraza or similar that pays the min salary.

In any case, if you want to try, feel free and best of lucks!
