you do code to read a microsd card in croatia.
No I don't and I'd guess that many others don't either. Stop spreading rumors about us.
I see no reason to suspect that reading a micro SD Card would be any different in Croatia from anywhere else in the world.
If, on the other hand, you are looking for a developer in Croatia - you should look at the Consultant Database:

(unfortunately, there are no entries for Croatia).
