I'm AWS and mySQL certified. I currently run a aws based cloud network with over 50 ec2 instances and uses Amazon RDS on some of them, and others which simply use centralized databases. This network has served over 5,000,000 users logging in to use the services, I understand virtualization and container based technologies very well. I'm also extremely good with writing and understanding very complicated high performance mySQL queries and setting databases up using high performance engines like innoDB (mySQL)
