...We are in Transylvania, and Transylvania is not England. Our ways are not your ways, and there shall be to you many strange things... Loneliness will sit over our roofs with brooding wings... It is a strange world, a sad world, a world full of miseries, and woes, and troubles...

"The only good is knowledge, and the only evil is ignorance." Herodotus

I'm just a lucky guy who was born surrounded by IBM computers and walls of floppy disks. My dad was a COBOL and BASIC programmer back on the day, and he used to take me into the company’s server room where he worked. That’s where I met one of his colleagues, the classic '80s German hippie nerd, long hair, big beard, cool vibes, and a sharp mind. One day, he sat me in front of a terminal and launched Prince of Persia on DOS. From that moment on, I was hooked to the scent of warm silicon, the blipping chiptune sounds, and the hum of machines. Back home, I never left our IBM 5170 and PS/ValuePoints. I learned DOS, Windows 3.0 and just kept going from there.

Today, I’m a Network Engineer with hands-on experience as a Level 3 NOC, Senior Network Engineer, Network Designer, Wireless Specialist, and Technology Delivery. My main focus is on Ethernet (IEEE 802.3) and Wireless (IEEE 802.11) networks, covering deep troubleshooting, network analytics, security, support, configuration, performance optimization, and network design. But my path has also touched backend programming, scripting, database administration, pentesting, and ethical hacking. Over the years, I've worked across high-density and global network environments: international airports, hospitality, healthcare, retail, transportation, enterprise, education, government, and globally connected high-availability data centers and branch offices.
