About Me

I have always liked computers from a very early age. I've spent most of my time both personal and professional around them.

I built a small HomeLab environment with a few servers and clients where I do all my tinkering with various Systems and IT Solutions mainly based on Vmware ESXI, Proxmox,Linux and BSD Systems.

I share more about my HomeLab and what I do with it over at my blog dedicated to it at https://blog.viktormadarasz.com

I also like to Train and Workout 5 times per week.I also like running including trail running.

My Experience in Linux & Windows System Administration

In my actual position at GeesinkNorba Group I am working as a Senior System Administrator as part of a two man team. The environment is close to being a 99% Microsoft exclusive ( Windows Servers, Hyper-V , Sharepoint , Office 365 Online including Hosted Microsoft Exchange solution among other things). I did manage to implement a few Linux servers in the environment ( Zabbix Monitoring solution and a Centralized Log Server )

In my previous position at Shadow Robot I was able to focus on working in a near 100% Linux and Open Source environment as a System Administrator.

These technical skills however were developed a long time ago on a personal level through self development and studying combined with a lot of time spent in a home lab with a 42U rack of physical servers, cisco switches & routers and many virtual machines using vmware & kvm technology.

I assume that I have spent now more than 6+ years with Linux & Windows servers in my lab I have built for myself and eventually expanded it to the cloud as well onto a dedicated server based on Debian running Proxmox on top which runs my production virtual machines. One example of that would be the one which runs my CV website at https://cv.viktormadarasz.com (AlmaLinux+NGINX) or my IT based weekly podcast in english at https://tsr-podcast.com which still runs on CentOS 7+NGINX.

The first Linux distribution I’ve ever installed was Red Hat Linux 5.0 in 1997 and from there on gradually after many years I have made the switch from Windows OS first to Mac OS X then eventually to Fedora Linux ( Red Hat 1:1 compatible) on my main computer I use daily.

My personal and professional choice for server OS is normally Linux first Windows second if the requirements and other variables such as compatibility allows it.

Right now my plan is to expand and to solidify this knowledge regarding Linux in a form of a certificate of RHCSA to further raise my professional value in the future and to balance out the lack of possibilities I was presented with so far during my professional experience.

Volunteer Work

I host two weekly podcast one called TSR - The Server Room Show - about IT & Technology in English and another one called La Tercera Pata del Gato in Spanish with my friend Antonio Garcia Hernandez about the life and experiences as a foreigner living in Madrid, Spain.
