The deployment folder seems like "the whole lot of stuff that makes the deployment work".
As for the rest of the code, we can organize it by domain (ie. domain = infra here) :

/backend
    package.json
    .env.*
    Dockerfile
/app
    package.json
    .env.* 
    Dockerfile
docker-compose.yml
docker-compose.prod.yml
Makefile

As for all the docker settings and conf files that are not directly linked to my project (e.g. nginx), I like to regroup them in their own .docker folder:

/.docker
    /nginx
         nginx.conf
    /postgres
         /data
         pg.conf

What's behind "app" and "backend" in your example ? Seems 2 differents things for me so we don't need to share a common docker compose file between each ?
