It does not eliminate code reviews.

In practice, you should have at least one independent reviewer who did not actively worked on the PR.

That reviewer should also download the entire code, run it, make tests fail and so on.

In my experience, it's also good that this is not a fixed role "the reviewer", and a responsability everyone in the team shares (your next task should always be: review someone else's work, only pick a new thing to do if there is nothing to review).

This practice increases quality dramatically.
