A friend of mine is looking for a remote internship opportunity for the summer.

I am not familar with the places one has to look for one so I came to ask you if you know any good platforms he can sign up for or if you are awareT of any concrete offers.

He's based in Sofia, Bulgaria but he's studying CS in Linz, Austira right now. He's looking to work with C#, Java primarily. He's already gone through a 3 year bootcamp where he learned C#.

Thank you.
