Tech Lead Cyber Security | Exploring the digital & physical world.
Hello, I'm Thomas and live in Siegenfeld near Vienna, Austria. Professionally, I work as Tech Lead Cyber Security, DevOps Engineer, Network Engineer and System Administrator.
These roles allow me to live out my passion for technology, IT security and network technology on a daily basis.
In my free time, I dedicate myself to programming versatile projects, operate an extensive homelab and keep fit through fitness, which I like to combine with technology and photography.
My passion for system administration, programming and IT security has accompanied me since my youth. At a young age, I started developing websites and expanded my knowledge in various programming languages and technologies over time. Today, I combine my technical skills and experience with my personal interest in IT security and data protection to develop innovative solutions and optimize existing systems.

On this website you will find further information about my previous professional activities and projects.
Apart from technology, I am interested in photography, fitness and volunteer in the village community of my place. Thanks to my technological curiosity, I integrate my knowledge and skills in these areas to achieve unique results and fully embrace my passions.
My hobbies, hiking and photography, perfectly complement each other, especially for landscape and nature photography. A selection of my recent shots can be found under Interests or on my profile on Pixelfed.

In addition to my passion for technology and photography, I am also fascinated by movies and series, especially science fiction like Stargate, Star Trek and Marvel - content that focuses on technology, science and a certain humor.

In my blog, I regularly share technical insights and experiences from my everyday life - from routing to VPNs to backup strategies. Here is an excerpt of my latest posts:
