One example that covers almost everything listed above would be this site. For more on ArrCay, checkout the Home Page or the ArrCay Site Help Documentation
Another example would be my plain old website listed under "HomePage:" in the sidebar to the left (on mobile screens the sidebar is expanded by hitting the right arrow in the menu bar above). Also found in the sidebar profile under "Identities:" are links to my github and codeberg pages... For whatever they are worth since I mostly use my own private Gitea server; I don't really care much for github - it's gone downhill since M$ bought it, but most of the open source world still uses it so...; and my public commits to codeberg are quite infrequent. A resume link and additional details (!more keywords!!! than those listed below) can be found at the cover.php page on the 7t4 site.

The following is a keyword list of technologies running on systems which I currently manage [not exhaustive]:
Slackware, Debian, Raspbian, Alpine, Proxmox (KVM, Qemu, LXC), Docker, Nginx, Caddy, PHP, Redis, PowerDNS, Bind, mail(postfix/dovecot/etc.), iptables/nftables, Wireguard, MySql/MariaDB, PostgreSQL, OpenWRT, ESP32, C/C++, UBXLib, Gitea, SignalK, MQTT
