Perfect replacement of Google photos for my home server

So I recently got into making my own server out of a spare laptop that I had lying around. I've configured a lot of stuff on it like jellyfin, casaos, arrs etc which fit my use case. I also connected it to the internet using my domain and authentik + cloudflare for security. Now what I want to do is create a sub domain lets say photos.doman.com which houses a google drive like interface to show all the pictures I have stored on my server. Any suggestions are welcomed.
