Multiple people working with docker in 1 droplet environment

My question is, I have a droplet environment. Here with my team, we write backend frontend and datapipline codes in the docker environment.I can’t understand is this. Who should do docker compose up ? When I adduser for each different person? Because if person a does this, people b and c cannot make changes in this compose in their own file. My second question is as follows. Since we are working in the same environment, let’s say the backend environment crashed for a while. Will the frontend not be able to work until the backend is up again? So what I want to do is, can everyone work in their own private docker compose file, even if they have only one docker compose.
