I was extremely challenged by the work at Layer 7 Technologies as their OS Developer. I bridged the Developers and QA techs in defining and maintaining the server based embedded networking appliance operating system. My biggest accomplishment was to drastically decrease the build time for building system images. I took a “by-hand”, very prone to human error system and turned it into almost a completely automated system based on Kickstart and a variety of scripts and utilities.
I ensured that the OS was STIG (US Military secure specification) compliant and developed an SELinux enabled build of the system. I was also responsible for the development ESX server versions of the software. Because of my past sysadmin experience, I was pulled into maintaining the development servers and company network services.
