About me: Sergio Fernández

Hey there 👋!
I'm Sergio Fernández, a Senior DevOps Engineer specialized on Kubernetes, GCP and AWS based in Murcia, Spain.
Nerdy on the inside, I'm driven by curiosity and the need to continuously learn new things. I have a particular obsession, and it is to read +1,000 news daily (yes & yes, I skim sometimes, otherwise it would be impossible for me to cope. But I really enjoy reading well-presented articles—especially the trending ones appearing in Hacker News).
