About
I’m a network engineer, educator, and content creator passionate about making computer networking accessible to everyone. I believe that understanding how networks work is fundamental to building better systems and applications.
My Journey
I started my career in network operations, working with enterprise networks and ISPs. Over the years, I’ve worked with everything from small office networks to large-scale data center infrastructures. This hands-on experience taught me that networking doesn’t have to be intimidating—it just needs to be explained clearly.
