Doing all that on your own server is fun and not too hard IMO. Like if you can learn React this is orders of magnitude easier but perhaps way more boring or beneath people?

I mean for DB I run a prod mariadb on hetzner and it is arguably easier to install and setup than say things most devs use, say vscode. Had to tune a couple of things (number of allowed connections for a user) but lots of good docs out there to help.
