PROFESSIONAL EXPERIENCE:

Confidential

DevOps Engineer

Responsibilities:

• Management role in IT while still completing hands - on DevOps work
• Present results and plans for both DevOps and IT at each sprint review
• Manage the Jenkins server used to build all software. The Jenkins server utilizes OpenStack instances and Docker as well as build slaves running CentOS 6, CentOS 7, SUSE 11, and SUSE 12
• Responsible for the tickets on the DevOps Kanban board
• Wrote a command-line utility to interface with our OpenStack environment to make it much simpler for employees to use by resolving instance names to IP addresses, selecting the appropriate user for a given image, and patching issues on problematic images
• Built custom RPMs like hwloc or python27 to include with our products, so that our customers didn't have to build them from source
• Upgraded the legacy installer to work on CentOS 7 and SUSE 12 (prior to the new installer being written)
• Designed the process for doing a non-Internet-connected install of our product (used at secure sites)
• Automated the process for posting new download to our website, which took an error-prone process that took about 4 hours and allowed it run perfectly every time in 15 minutes.
• Major Project - Automated Installer:
• Using Ansible playbooks and Bash, designed, wrote, and tested an automated installer for the Confidential product suite, which installs the company's nine products onto a supercomputer cluster in less than an hour (a process that would take a trained employee more than 2 work days to complete)
• It prompts the user for 3 types of input: The cluster inventory, the desired set of products, and all configuration options. The installer takes that information, and installs it across a cluster of any size (from one node to thousands).
• Authored more than 50 Ansible playbooks which install all pre-requisites and requested Confidential products, connect products to databases and to each other
• Installer was built to work on RHEL 7, CentOS 7, RHEL 6, CentOS 6 SUSE 12, and SUSE 12 SP1
• Helped design a web-based user-interface for collecting user input and run the installer. After starting the built-in python web-server from the command line, the entire install can be run from start to finish from the web interface.
• Wrote automated tests for the installer which create small clusters in OpenStack and run the install from start to finish. Between the 7 product options, 6 supported OSes, and 4 different cluster sizes, a total of 168 clusters are stood up and torn down for testing
• Project took 6 months and was released on-time with version 9.1.0 of the Moab HPC Suite
