In addition to development, there is always a tone of work related with the system that cannot be avoided unless paying big bucks. Do not forget the basics for operating systems: there are thigns that are absolute basics: - bash/linux scripting, understanding - usage of basic linux commands, grep, awk, sed... - the basics of posix (stdin/out/err pipes, stderr) - Monitor your system: observe CPU/network - Configure firewall, ssh services, cronjobs, set up a systemd job And from here how to deploy anything with the stack/framework which is popular this year, kubernetes, docker or ansible or whatever infrastructure it is in the backend. Very rarely someone works "just coding".
