I have 20 years of Linux experience, so I've been doing this for a long time. I'm maintaining 3000+ KVM virtual machines for a large retail customer and deployed thousands of Linux containers. I'm also maintaining Linux servers for many companies with their entire infrastructure on AWS and GCE. I know how to monitor and optimize LAMP and LEMP stacks and I've been doing WPO as long as I can remember. I'm very security conscious and an automation enthusiast.
