Hello. I am pretty new to UpWork. I have only had one job. I am trying to improve my profile. Can I share the web address for previous jobs I have done, if I have the client's permission? Thank you.
Yes, you can web addresses as long as they do not contain contact information for you. I would continue doing what you have already done, by adding these examples to your portfolio. You can post screenshots and a description along with a link to the active site.
I hope this helps!
