Introduction

I am an engineer. My first contact with computers was when I was 11 years old, when I learned to program Basic for Spectrum 48k. Since then, computing science has always been a hobby in my life. At university I studied Civil Engineering, and in my first jobs I applied my programming and systems knowledge to Civil Engineering projects. I acquired much of that knowledge at GPUL, the Linux users group of the University of A Coruña. As of 2012 I started working on purely IT projects (but I apply on them the hard work, scientific thinking and self-learning that characterizes us as civil engineers). Like many IT people, over the years, my jobs have evolved from traditional sysadmin to DevOps/Platform Engineer, which is my current position.

Interesting facts about me

Free Software activist

I meet the Free Software movement in 1998, the same year I joined to GPUL-CLUG (Coruña Linux Users Group). I actively participated in the activities of that group until 2012 when I moved to Madrid. Also, I have been collaborating with other FLOSS projects like The Free Translation Project, Fedora and pkgsrc.

Homelabber

I built my own homelab on a 12U-rack. I run there a pfsense appliance, an HP ProCurve switch, and some server nodes (HP Proliant, Supermicro) that are my 2nd level backup (built on FreeBSD) and my private cloud for develop and testing (built on SmartOS).
