This allowed my team to quickly analyze results graphically using tools like Kibana and Grafana to find inconsistencies with our test runs. * I made my team more efficient and improved onboarding time by creating a maintaining a wiki that documented all my automation thoroughly, customer environments, best practices and common troubleshooting techniques.

This also enabled me to build infrastructure with code and made creating test environments repeatable and consistent. * I automated the installation and configuration of DNS, DHCP, PXE and other infrastructure systems to bring a base physical Ubuntu system into a KVM Hypervisor running virtual machines with Vdbench, testing filesystems against a SolidFire cluster in under 15 minutes.
