Hi, I’m Christopher. I am an IT professional and enthusiast currently working as a High-Touch Engineer at Cisco based in Frankfurt (Germany). I have a deep passion for technology, thriving on meaningful discussions about digital transformation, strategic IT leadership, and innovative business solutions. My journey in tech has taken me from the trenches of IT System Administration to the strategic world of Cybersecurity Consulting, and now to the heart of enterprise networking. This diverse background has given me a holistic view of the IT landscape—allowing me to understand not just how to build networks, but how to secure, operating and troubleshoot them effectively.

I created this blog to document my technical journey. Here, I share the lessons I learn while solving real-world problems, the notes from my certification studies (like the CCNA and Security+), and my experiments with network automation.

Whether you are here to troubleshoot a specific protocol, find study tips, or just geek out over network diagrams, I hope you find something useful. I am always looking to connect with fellow engineers and tech enthusiasts, so feel free to reach out!
