# Rick Rackow
Site reliability engineer scaling systems with Go and author of Operating OpenShift.

## About

Rick Rackow builds and operates distributed systems as a site reliability engineer at Codesphere. He focuses on the realities of production environments across Linux and container infrastructure. He is also the author of *Operating OpenShift*.

Rather than relying on default assumptions, Rick cares about how code behaves under constraints. He frequently unpacks the technical quirks of cloud computing, like breaking down exactly how Go handles concurrency and parallelism inside CPU-limited containers.
