A lot of people posting complex things. All you need is SSH.

    ssh [e-mail]
    mkdir project-1.git
    cd project-1.git
    git init —-bare
    exit
    git remote add alternate [e-mail]:project-1.git

For the syncing part. If you don’t want to do it manually, you can add multiple destinations on the same remote. Someone already mentioned it here, https://news.ycombinator.com/item?id=23818609, https://jigarius.com/blog/multiple-git-remote-repositories
