Who am I

My name is Sebastien Wains.

I'm a cloud and infrastructure senior consultant at Red Hat, the world’s leading provider of enterprise open source solutions.

I'm a Red Hat Certified Architect (RHCA). My certification ID is 110-643-822.

What I have been up to in the past

In the early age of this blog, I was really into Linux, Postfix, OpenVPN and Asterisk.

After changing job I was in charge of several hundred servers. I spent a lot of time automating and orchestrating system administration and management tasks with tools such as Salt, Salt Cloud, Python, Git/Gitlab, Mkdocs, Rundeck, Jenkins, Artifactory, Nexus, Postman, Red Hat Satellite, iTop, Graylog, Redmine, etc.

I have talked about Salt at Jeudis du Libre conference. Check my Github for the decks.

At the personal level

I automate things whenever I can! I'm a big fan of Node-RED, Automagic on Android, Alfred on Mac, Ulauncher on Linux, and hackable connected devices.

Publishing on this site is also automated.

My desktop environment

I use i3. I wrote about my desktop environment here.


This site has gone through five major design revisions:

A bit more about me

I like building simple, powerful, resilient, secure and automated infrastructures. Preferably based on open tools and protocols.

I care about security and privacy.

When I'm not busy at the computer, I travel, hike, ski, camp out and take photos.

I'm an INTJ: INTJs are known as the "Systems Builders" of the types, perhaps in part because they possess the unusual trait of combining imagination and reliability. ~ Marina Margaret Heiss
