Hello and Greetings from Chile.
I've always liked technology since I was a little kid, my father is an IT technician, so we always had computers around our house.
I'm 26 years old, and I'm an ESL Teacher working on a technical support shop In Valdivia, Chile as a receptionist. I'm the only one here who knows English, so I was told to look for some solutions for some of the problems that our costumers present in their laptops or desktops.
So that's it, I hope that you can help me so I can help you too in the futureComment

Hi everyone,
I'm a twenty-something guy from the Caribbean, and I still vividly remember the day I saw my first RAM stick. My cousin left it inside a glass cup because it went bad, and I was instantly hooked. That moment sparked my fascination with hardware, and ever since, I've been captivated by everything related to electronics.
Growing up, I struggled in school—not because I couldn't learn, but because I was pushed to follow paths that didn't align with my interests. Society often emphasizes schooling to mold you into someone you might not even want to become. Back then, I was just a kid exploring the world and figuring things out.
Now, I know exactly what I'm passionate about: electronics. I love understanding how they're built, fixing them, and finding ways to reuse and repurpose tech for a more sustainable planet. I'd even say it feels like my calling.
