is it ok if I share a project link hosted on GitHub pages as my portfolio?

Hello everyone,

I am new to Upwork and I wanna share some previous work as my portfolio on Upwork. but, some of them have no individual domain. I have hosted a few of them on a few subdomains of my personal domain which includes my name. also, few of them I have hosted on GitHub pages. you know GitHub has a service to host our website for free. and all of these website domains contain my name.

so, I am confused is there any problem if I share those links as my portfolio so that clients can go and see my works?

thank you.
