Benjamin Haertel Avatar

Hi, I’m Benjamin! 👋

Welcome to my corner of the internet. I am a passionate multi-vendor network engineer and architect using modern technologies and automated workflows - from on-prem to cloud infrastructures.

🛠 What I Do

Currently, I work as a Senior Technical Consultant at NTT DATA in Berlin, Germany.

My core expertise includes:

  • ☁️ Designing and Building state-of-the-art Network Infrastructure
  • 🧠 Deep Knowledge in Routing/Switching Technologies in Campus, DC and Hybrid Cloud Environments
  • 🤖 Embracing Automation & DevOps Principles and integrating them into my Workflows.
  • 📚 Continuous Learning, Technical Writing and Knowledge Sharing

📝 Why This Blog?

As the worlds of Networking and DevOps converge and the complexity of modern infrastructure continues to grow. I started this blog to:

  • Break down complex solutions and architectural concepts into digestible insights
  • Share practical insights and guides based on the experiences that I made throughout my professional career
  • Document my learning journey.

I’m trying to write the blog posts for my “past self”, explaining things the way that I would have liked them explained to me. If it helped me, it might help someone else out there too.
