Echoing what others have said: just post your stuff. If you're not intentionally publicizing yourself or your work, I can nearly guarantee that no one will ever even look at your work. I've been putting up my little personal projects up on my GitHub for over ten years, and yet no one's ever come around to look at them except when I intentionally posted links to those projects on places like HN.
No one's going to look unless you ask them to look. If you already have a big audience (over 100+ people daily using things you've built) no one is going to "get curious" about your projects. So just post them so folks can see them.
