Is it possible to add projects to the portfolio that fall under non-disclosure?

Question

Portfolio

I have managed to work on several projects at the moment, but I don’t know if it’s possible to replenish my resume with them. The fact is that under the contract, most of these projects completely became the property of the customer and, in fact, I can’t talk anywhere about the code of these projects, not to mention uploading to github.
If anyone has asked this question and found the answer, please share! Also, it would be cool if people from the sphere would share their opinion.
Thank you!

Answer 1

You have the right to refer to them, and it is better for you to ask the customer about placement.
