Welcome to Arnau Guiteras’ website

Personal description brief

I am a Computer Engineer with 20 years of work experience dedicated 100% to the platform.
I started my working life as a SysAdmin (Systems Administrator) and currently spend six years as an SRE (Site Reliability Engineer) applying the DevOps methodology. I was recently promoted to a team leadership position.
I consider myself a lover of new technologies. In my free time I like to apply home automation to my home, go on motorbike trips with my friends and enjoy good food.
