Having built this website from scratch, I would say I'm decent with HTML and CSS, as well as shell scripting and Python. Furthermore, I'm also capable of coding in C and Java. All while using Git for version control, of course. Although not software related, I've also done some work with VHDL as well.
I'm very experienced with Linux, having used Arch and Debian as my daily drivers the past few years.
Aside from that, I've also dabbled with Alpine and I know my way around ProxmoxVE, since I mainly use that for my homelab.
I'm also no stranger to deploying and maintaining various kinds of software and services, which includes working with Docker.
For example, I currently host an Nginx, SMTP/IMAP, Wireguard and Nextcloud server, among many others as well.
For more information, consider taking a look at my homelab page.
Although this website is entirely in English, I also fluently speak German, because of my bilingual upbringing. And while I may be familiar with the software side of PCs, for years I've also been building my own Computers. In my opinion, I'm also not too bad at handling a soldering iron either.
The Take away: I'm a bit of a computer nerd.
