If you're willing to associate your username with your personal identity, you could link to your projects/CV in your profile. Other commenters may be able to identify what recruiters are looking for and why your resume was dismissed.
Also, to the point of the post, do you consider whiteboard interviews to be good or bad for your situation? With covid it's harder for companies to find which applicants should be interviewed in the first place, and short questions are helpful for filtering out people who can't code at all.
About the leetcode thing, yes, I used to be pretty code. If you send me a link right now, I might not be able to do it, since I am living under huge stress right now, but with 1 week or 2 training I can get 80-90% in the coding challenge easily.
I'm not in a position to help get you an interview at the moment, so I'd feel uncomfortable asking for your resume. Participating on Hacker News and GitHub is an avenue for networking. Without linking to information about yourself you may not be able to take full advantage of that.
I'm sorry to hear about your stress. The worst part about the recruitment process is that it doesn't put folks in a typical development situation. I hope you're about to find something!
