This is a bad question cause it comes off as judgmental and everything... But what do you think you are getting out of a "platform" when it comes to learning a language? I agree with keyle that you'll learn more working on a real project than doing a platform curriculum that is usually designed around beginners. Just my personal hot take. I like exercise I suppose if that's the sort of thing you really think would be helpful. The only reason I'm giving you this answer is cause you said explicitly "for senior devs". I don't really know any senior devs personally (that would admit to) using "platforms" or exercises to learn new languages. For me, I open up the docs and start writing a project, and I think that usually gets the job done learning a new language a bit faster. Most platforms are way too beginner oriented, and you'll rarely get anything that requires more than a small amount of code...it's tough to learn a language very well until you have more than say 1000 lines and are seeing how the tooling and modules and whatnot really work on a realistic size of project...
