Sumary

I’m an open source enthusiast with more than 20 years of experience working with Linux. In the last years I have been focusing on Kubernetes, Cloud Computing (AWS, GCP, Azure), DevOps, MLOps (DevOps for Artificial Intelligence) and SecDevOps. I also write some code in Golang and Python.

In this blog I will publish technical articles, cheat sheets and procedures, regarding Open Source, Linux, Kubernetes, Cloud Computing, Edge, DevOps, MLOps, SecDevOps, GitOps.. whatever OPS!! All the content and opinions in here are my own.
