As you only mention git and not any git hosting. I would say you could easily use git hooks. Fir you and probably ask everyone in your team to install the same git hooks to have a chance to review changes before they are commited.

For my team there is an init-git-repo.sh shell script in our repository. When you execute it, it will install all the git-hooks fir your local repository.

You can use them to add checks during commit, merge, etc…
