Welcome! My name is Sanjay Singh, and I’m the founder of networkbasics101.com.
I’m Sanjay Singh, a Network Architect and Cisco Certified Internetwork Expert (CCIE #10534) with over 28 years of hands-on experience in network engineering and cybersecurity.
I started this blog to share my industry knowledge and passion for the fundamentals, with a simple goal: to break down complex technology into clear, easy-to-understand concepts for everyone.
Over the past 28 years, I’ve lived and breathed networking. My journey has taken me through every phase of a network’s lifecycle—from architecting and designing solutions, to implementing infrastructure and managing day-to-day operations. Earning my CCIE certification has been a defining milestone and a foundation for everything I do.
In recent years, my focus has expanded into cybersecurity, where I apply deep networking expertise to help protect critical systems and infrastructure from evolving threats.
I also actively leverage AI in my daily work to improve efficiency and solve problems faster. I’ve designed and built AI-driven solutions that can:
- Analyze network and system logs
- Identify root causes of issues
- Reference knowledge base (KB) articles
- Provide suggested fixes and next steps
These AI workflows help automate repetitive troubleshooting tasks, reduce time to resolution, and allow me to focus on more complex challenges.
After decades in the field, I created this blog because I believe mastering the fundamentals is the most powerful advantage anyone can have in technology.
Whether you’re just getting started or already experienced, my goal is to make networking, cybersecurity, and now AI simple, practical, and accessible.
