      I spend most of my life pressing buttons on a computer to change its
      pattern of lights. I wear many hats and change them regularly. I want to
      undestand the world.
    MARKDOWN

      I follow the traditional DevOps school by creating, maintaining, and
      operating software systems using Ruby on Rails, Chef or whatever it takes.
      If you want to reach me, <a href="mailto:#{email}">write me an email</a>.
