Frontend challenges with deadlines

Hey IH,
I was thinking of building a platform like codewell and Frontend mentor but with the feature of deadlines. As I feel that is something I am faced with alot in my 9-5 job.

I think having a platform that expects deadline would be beneficial for training newbie FE devs and ever experienced Devs to deal with real life job expectations.

Would this be a good idea?
Is there something out there already?
Is it something you would use?
Any information is very helpful.
