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 last position at Shadow Robot I was able to focus on working in a near 100% Linux and Open Source environment as a full time 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.

Shadow Robot

System Administrator September 2020 - March 2021

I worked as a System Administrator for Shadow Robot.During my day to day responsibilities I was the system administrator for a few linux servers, mostly debian based which ran a couple of services (openvpn, svn, cron and others). I performed weekly backups on these systems together with rutine maintenance tasks when it was required.

I handled the company's email flow with Google Workspace's admin console and their Microsoft 365 licenses for their Microsoft Office Applications.

Remote management was done via ssh or Teamviewer's Management Portal. Bitdefender Central's Gravity console was used for antivirus under Windows/Linux/Mac.

Remote KVM tools and UPS were in place to ensure remote support and continued service for critical infrastructure in case of a momentary loss of power.

End user support was done by me with a user base of around 60 people working from home and remote offices.

Providing these users with the training courses on various topics like Introduction to Linux, Cyber Security Awareness or how to use certain company specific software and applications were prepared and hosted by myself.
