Duties also include SAN provisioning, mapping and configuration. Was also responsible for F5 configuration, maintenenace and troubleshooting. Emphasis placed on VMWare administration with primarily Red Hat 6 virtuals and some x86 Solaris.– Project lead on multiple projects. Responsibilities included server staging and configuration, resource allocation (physical and personnel), time management and business presentation.– Infrastructure lead on STS project. Worked directly with developers in an agile environment to build up the development and production infrastructure. This included permanent servers and temporary virtuals that the developers could create themselves for unit testing. Provided best practices consultation to ensure that infrastructure and development needs didn’t contradict each other.
