Hey, I’m Luis!


I am a Linux Administrator with Cloud/DevOps/Security skills working at Rackspace, where I am focusing on learn and apply a Cloud Native techniques, in Multicloud Environments, using agile methodologies.
I am actively contributing to Open Source projects and define myself as a Linux enthusiast who loves to work and experiment with Open Source technologies while I am learning,and trying to apply best practices.
I learn new stuff every day and I like to share; sometimes I write about it on this blog.
