AWS and Unix expert. Have set up auto scaling servers with Chef scripts and can build SOA which is basically multiple stacks that can scale horiztonally and vertically based on server type. This includes data modeling and database architecture (sharding, raiding, RDS, NoSQL, etc). I have developed systems that accepted a billion records a day and also systems that need burst traffic. I understand the cost of a small company ( have started by own) vs the cost of scaling. This is critical when building out servers.
