Not a list of skills but things I'v done and how
First of all my servers are basicaly 3 types Proxmox cluster, k3s cluster and unfortunantely Windows. For containers prefer lightwaight portainer, but on few servers prefere Rancher for bigger functionality (as k3s orcestrator). Loadbalancers - nginx, metalLB and traefik for small things

Network infrustructures as CISCO recomends, isolated from outer world networks behind firewals separated within each other whith by vlans, comunication between locations trhoug ssh tunnels with RSA keys

Web sites - bare php, wordpress, joomla (there were a lot of them, mostly freelance and now i avoid frontend)

Few android apps for corporate and personal usage wrote on java, for API it depends: php/python for simple database requests, java for others

Simple php telegram bots. It turned out to be more convenient than a web service or an android app for users
