Hello,
I need developers in the mentioned programming languages to make 8 code challenges from scratch (like an exam's problem/solution).
You must be expert at your field and have a good english, You are NOT allowed to pull up any existing challenges from the internet. Everything needs to be custom and written from scratch.
I'm going to pay a maximum of $60 for 8 code challenges.
You don't have to know all the mentioned languages, I'll choose a developer for each one.
P.S. Expertise in OOP in some languages would be necessary.
