Previously, Ross was a Senior Technical Training Engineer for NGINX, where he completely redid the Fundamentals learning track, authored a number of Getting Started guides, and taught a number of customer engagements to help new NGINX customers take full advantage of the platform.

Before NGINX, Ross enjoyed a few years at Linux Academy/A Cloud Guru where as a Senior Training Architect, he authored the SUSE Certified Administrator and Engineer courses, did the Red Hat Certified System Administrator Labs, created many additional courses on systemd, VIM and the screen command, and wrote and reviewed way too many exam questions.
