Sergio Fernández

GeiserX
Murcia, Spain

Hi there! 👋 I'm Sergio Fernández Rubio (GeiserX), a DevOps Engineer specializing in Kubernetes, GCP, and AWS, based in Murcia, Spain.

My journey started when I was just a curious 👦🏻 12-year-old kid, begging my mom to buy me the book "Hackers 4 - Secrets & Solutions for Network Security" (freely translated from Spanish) published by McGraw Hill. I still get chills thinking about it!

Honestly though, after reading it, I realized I'd prefer building things rather than breaking ⚡ them. Fast forward over two decades, and here I am—fully embracing life in the cloud, building and scaling apps, and loving every second of it.
