About Me

Hi. I'm Raj Chettri.

I'm a cybersecurity professional with a structured mind and an insatiable curiosity. I've served in the U.S. Army in cyber operations, and my background spans from repairing attack helicopters to studying how artificial intelligence and regulation intersect. I believe in the power of continuous learning and practical application — which is why I write, build, and share in public.

What I Do

My work sits at the intersection of cybersecurity, technology, and education. I'm passionate about understanding how systems work — and how they break. Whether it's analyzing network traffic in Wireshark, building Python scripts to automate security tasks, or studying for my next certification, I'm always working on something.

Currently, I'm deepening my expertise in ethical hacking (pursuing CEH), building out my home lab for hands-on security research, and exploring how AI intersects with cybersecurity — both as a tool and as a threat vector.

Why This Site

This site is my living notebook. It's where I document what I'm learning, share practical guides, and think out loud about technology and security. I created it because I believe that teaching is the best way to learn, and writing forces clarity of thought.

You'll find cybersecurity deep dives, certification prep guides, tool reviews, and the occasional reflection on productivity, learning, and life in a fast-moving tech world.

Beyond the Screen

Outside of work, I enjoy road trips, casual writing, hacking together Python scripts for fun, and learning about technologies that actually solve problems. I'm fascinated by startups, strategy, and long-term investing. I like my ideas clear, my coffee strong, and my file backups automated.

Thanks for stopping by. Feel free to reach out — I'm always up for a good conversation.
