• Improved stability of Windows 2008 and 2012 images used in Openstack by identifying and correcting a race condition that would intermittently cause an instance to reboot during setup, rendering the instance unusable.
• Identified filters that could be removed from nova scheduler and cut the time it took to schedule against 700 nodes from 20 seconds down to 5, reducing the time it took to create an instance in large scale environments.
• Built out and evaluated several Proxmox clusters for possible usage with Cisco's InterCloud Services.
• Configured RHUI clusters for tenant use and assessed its viability for use as a service to customers using RHEL VMs.
• Wrote Ansible playbooks and executed them to change configurations and manage cron jobs on hundreds of servers. Ran ad-hoc Ansible commands to identify servers needing fixes applied.
• Managed script and playbook changes with Gerrit and Jenkins for CI/CD.

• Created Ubuntu-based Ceph cluster for ESXi hosts, tested performance of iSCSI vs RBD to Ceph block devices used by ESXi VMs.
• Implemented SaltStack to manage Linux VMs and quickly provision new Ceph nodes and VMs.
• Utilized Ceph RBD snapshots to manage testing of automated database schema and data conversion for major database upgrade. Upgrade of production database was accomplished with zero errors.
• Wrote Python/SQLAlchemy script to test for missing foreign keys through the course of a major database migration to ensure data integrity.
• Installed Observium to graph system performance and added checks to Nagios to properly monitor production and development systems.
• Updated VM configurations and software to reduce number of service restarts from one every week to one or two per quarter.

• Gathered system requirements from clients for custom PHP modules and features.
• Tested new features against requirements and for proper integration with the core Centre/SIS software.
• Benchmarked and analyzed SQL queries, improved database performance through the use of views, stored procedures and triggers.
• Re-engineered database tables to normalize data.
• Tested PHP modules to make sure they completed data conversion and calculations properly.
• Wrote custom Python/SQLAlchemy script to import nightly data from Arkansas state reporting system (APSCN) into Centre/SIS.

• Installed and managed Citrix XenServers running virtual Windows 2008 and Ubuntu Linux servers.
• Managed project to completely replace aged student information system with web-based, centralized system that removed the need to copy data between schools.
• Streamlined state reporting processes by writing PHP code to generate the reports from the new centralized Student Information System.
• Supervised contractors installing cabling and hardware in new buildings to make sure it met requirements.
• Saved the district over $60,000 and reduced helpdesk issues significantly by outfitting 6 new computer labs with thin clients and terminal servers instead of using PCs.
• Increased WAN bandwidth between buildings from 1.5Mbps to over 100Mbps without incurring monthly service costs by installing Ruckus wireless bridges.

• Tested integration of ImageCast with other systems management software like SMS, CA Unicenter, and Desktop DNA.
• Performed ImageCast demonstrations and training for large corporations like HP, Target, and NEC and during trade shows.
• Worked with customers to define software requirements for new features and submit change requests.

Training of tech support in the testing lab worked so well that the decision was made to merge the testing and tech support departments. I was given the responsibiliy of managing this new department. In this capacity, I hired and trained new technicians, designed test cases and executed testing plans, managed lab Windows and Linux servers, and managed the.

I was given a permanent job with MicroHouse after an initial 6 month contract doing testing and QA for the company's software. My attention to detail and methodical approach made me well suited to QA. I was given more responsibility and in short order was managing all testing of ImageCast and DrivePro products. I maintained all the lab hardware and.

My foray into Testing and QA started with this contract job with MicroHouse, Intl. I Tested DrivePro and ImageCast software. Created test scenarios and set up lab hardware (PCs and networking) for testing DrivePro and ImageCast. Trained tech support personnel on software and helped with difficult support issues. At the end of the contract, MicroHouse hired.

This was my first job after the AirForce and was where my foundation for System Administration started. I remember the owner of the company thinking it would take me up to 6 months to learn to build PCs, but I was proficient at quoting all the parts for a new build and putting it all together in less than a month. My Air Force training helped me understand.

After two years of college-level chemistry at Colorado School of Mines, my electronics technician training started out a little slow with "An atom is made up of protons, neutrons and electrons." By the end of that 9 months, though, I had been exposed to every basic electronic device, both analog and digital, that there is. It's from this training that my.
