I'm a passionate technologist educated as datatechnican and waiter/sommelier in Denmark. I love spending time tinkering with projects of all sizes, ranging from software development, modern web-coding, deep-diving in interesting certifications, Capture-the-flag events in Cyber Security, working my skills in OSINT, pentesting, blue teaming, security engineering, and Linux / network administration.
I have been involved as volunteer in the Danish Youth Association of Science, UNF since 2007 creating and performing interesting learning-paths in the STEM educational-tracks for the youth, working four years in the national board as member and later as vice-chairman, and most importantly; I have from the beginning, been an integral part of the IT-team. I started by creating an unified participant-signup system in PHP handling hundreds of applications, and totally rewriting the hole thing the year after, as I had learned and gained a multitude of experience coding in PHP. Before that, applications was done primarily by classic "slow-mail", so a digital version was quite nice back in 2008. Further I engaged in the team-lead group and have participated in scratching our entire build of internal systems written in PHP from the period 1997-2010 as the technical depth was taking to much of our time. We rebuilded our internal and external systems with Python using the Django Web Framework - for a volunteering team, a task taking us almost 6½ years. But boy, was it great to release the new shining systems in late 2016, after about 60k lines of code (and yes, I wrote a new version of the participant-signup application system again..).
Besides the programming in UNF, I participated in the server administration. My many years of experience in Linux can greatly be contributed to this work. Starting with CentOS in the late 2000's and moving to Debian-based Ubuntu in 2012. I personally changed desktop OS from Window XP to Ubuntu around 2008, and haven't used Microsoft Windows as my daily driver since. Working in IT and primarily Cyber Security, Microsoft Windows' platforms is a must-know, and I use it in my full-time-employment job. But rocking Linux at home - it's a heaven, at least for me.
At home I love tinkering with my Linux-setup using my KVM-hypervisor configuration, where I strive to automate as much as possible using Ansible, implementing domain-capabilities with freeIPA and "general" home-labbing fun activities. I primarily use Debian-based systems at home, but administrate both Debian-based and Red Hat-based systems at work.
When being passionate about my work, I often find myself tinkering with new setups that I can use to perform evaluations, investigations, learning or really anything related the Cyber Security field. I have configured my own "MalwareLAB", where I securly can investigate malware examples, extract how they work, their IOC's and most important, how we as blue teamers can track, identify and eradicate those bastards trying to do malicious or nefarious things.
Being a part of the Cyber Security-field and IT in general, I love not leaving everything to the cloud - having full control over my own data is both fun, learning and provide some kind of safety-net, should some of the cloud-providers choose to change policy, change their offers or even go out of business. My homelab is ideal for that. I use Nextcloud as a private platform for all my files, notes etc., and serving it at home using enterprise hardware. My IoT-devices are only sending information to an internal MQTT / Node-RED / InfluxDB setup and multiple of the IoT-devices are being build up from scratch. Like, I mean scratch - designing circuit boards, assemble, testing and deploying.
I love physical media. My ever-growing vinyl collection has exceeded 250 pieces that I love to listen to using my "classic" analog stereo setup. Compact cassette and reels are definitely on the horizon!
So what is this blog about? Well - all the above.
Write-ups of CTF's I have participated in, info-blogs for waitering / sommelier (maybe don't expect a lot of those anymore - you know... time..), information-sharing on homelabbing, engineering for IoT-devices, analog sounds, vinyls, tech-certifications and everything in between.
