I am Carl Kittelberger, born in Germany in March 1995, still living in Germany. I am a software and web developer, both programming and administrating servers as a hobby and for my main job. Also, I am an electronic music producer and DJ — not sure if you ever heard of Trance or Techno, but that's the genres I involve myself with there.
The obvious ones:
- Denon DJ Prime 4 reverse engineering - Custom firmware to enable OpenSSH and other custom software, general reveng research.
- StagelinQ for Go - Interact with Denon DJ devices.
- Icecon - Administrate Q3-compatible game servers, e.g. FiveM, IW4M/IW5M.

- bsdiff C library wrapper for Go
- MediaLink IRC bot
- Football-Data API
Experimental, archived stuff:
At a very young age, probably of around 8 years, I got super interested in the BASIC programming cartridge for a VTech laptop I used to have. It amazed me, that I was just able to do anything I want in the world of software by telling my computer what to do with text. At some point, my father let me use our personal computer which was our very first PC and it was a Fujitsu-Siemens. I discovered that the Microsoft Office installation on it allowed me to write Visual Basic macros. I used it to write random stuff, especially though I was fascinated of its Form designer. This let me create pretty much any window I wanted to create, and it just absolutely blew me away!
During the coming time, I also developed an interest in writing websites. This software named Microsoft FrontPage introduced me to a range of designs that a website back in the day could have, and I got curious about how that looked behind the scenes in code. That's how I learned about HTML and CSS being a thing, and later on I wondered how websites dealt with these weird ?something=something&otherthing=something parts in the URL, which would lead me to PHP and JavaScript. I tried myself on all of those languages of course because how could I say no to creating anything I want inside a browser?
As I became older, we moved from our old 56k modem connection to a flatrate DSL line, and my family moved from a single PC to having multiple laptops, including me getting my own at some point. I learned through the Internet that Microsoft offered free tools for developing executables. I first hooked myself on “VB.NET Express” but later on tried myself on “Visual C# Express” as I started programming nearer to the system and running into limitations that the Visual Basic language itself had. This software and its follow-ups in the Visual Studio range were my entry point to 10 years of working with C# to write command line tools, GUIs, IRC bots, just anything I could come up with. I incorporated that knowledge when I also got access to my first server at the age of 14 to write custom tools to host APIs and some websites.
Much later, I broke out from the “.NET Framework” to discover other programming languages to compile executables, and I eventually settled with Golang for the time up to this very day. It is such a powerful, versatile language for developing CLI tools and server software, and there has been no reason for me to switch languages since for stuff like that.
If you're interested in that, start by checking out my SoundCloud profile. This is where I upload all the music and mixes I produce. From there you can find other links to follow me if you end up liking my music.
This is just the part where I mention stuff I use and do and that fits nowhere else on this README. Might remove this at some point.
- I currently use VSCode and its Insider version as my main code editor/IDE. Used to use Atom, Visual Studio, LiteIDE, Notepad++, PSPad and other GUI editors and IDEs before that.
- I am strongly pro-automation for a lot of software and web development things! I build and deploy with GitLab CI at work and with Jenkins for hobby stuff, but I intend to get a bit more into GitHub Actions as well.
- While I absolutely love working with Linux and know my way around to the point that I use Arch Linux, I am a power user in both Windows and Linux. On my Linux desktops, I intentionally use a theme that looks like Windows 10 to confuse people as a sort of in-joke.
- I love working with containers! Experimenting around with Podman but I would not want to lose my Docker Swarm on my servers. Also, using Fedora CoreOS as operating system for server containers.
- I virtualize on my servers with libvirt and Proxmox (both use QEMU/KVM behind the scenes). Looking forward to Proxmox's backup server solution since it has a lot of potential to improve QEMU VM backup experience for sysadmins!
