About

Hi, I’m Jorge.

This is my personal technical space where I write about networking, security, and how modern systems actually work—often by taking things apart and rebuilding them from first principles. Most of what you’ll find here comes from hands-on troubleshooting, experimentation, and the process of teaching myself topics I want to understand deeply.

I don’t claim to be an authority. I do care about accuracy, clarity, and reasoning things through until they make sense. If something here is useful, it’s because it was useful to me while learning it.

This site is less about polished answers and more about honest thinking, practical exploration, and sharing what I’ve learned along the way.
