Honestly, that is way too much for a junior.

I'd side-eye that list as senior .NET dev full stack.

You're asking one person to do frontend/js/css, backend/databases/Redis/MQ, and Python with all that math behind data-science, but i doubt he can understand and review all of this

Of course I wouldn't give all that to a Junior! It's just what they could expect to work with if they stayed long term.
