is there any material available that do code review of projects?

Hi All
I am learning C++ and wants to create/contribute C++ projects.
I know most of modern cpp concepts(till c++17)
but haven't confidence and also I want to follow some clean coding standards.

If there any material related to code review available on YouTube/Udemy/Coursera or anywhere that will be very helpful to me.

so, please tell if anyone have experience into this

Thanks in Advance to all of you !!
