SECRET US DoD Jeff Kois has been working as a Systems Administrator for the past five years. He joined StackFrame in 2009, and has been the sole administrator for a large, mixed Windows/Linux network. In 2008, Mr. Kois graduated from the University of Central Florida with a Bachelor's Degree in Information Technology, and is certified by Cisco, the Linux Professional Institute, Novell, and the Committee for National Security Systems. System Administrator StackFrame, LLC March 2009 Completed DoD information assurance audits in accordance with DISA STIGs and requirements. Planned and carried out network refresh to replace unreliable and aging network hardware. Resulted in a more reliable and secure network as well as a 50% performance enhancement. Acted as consultant to design and deploy a new network infrastructure to support a rapidly growing organization. Upgrades resulted in a 1000% network throughput increase, as well as enhanced scalability and security through use of VLANs and ACLs. Reduced the number of outstanding trouble tickets from 40+ to 2 or less on average. Additionally, the amount of time each ticket stayed open was drastically reduced, with most tickets being closed in hours instead of days or weeks. Designed and implemented network and server infrastructure to support secondary networks and contracts. Deployed Puppet, WSUS, and a local software repository to enforce client configuration and bring a regular update cycle to workstations on the LAN. Implemented a centralized log server and log monitoring in order to enhance fault detection and security auditing. Systems Administrator, IT Manager Sherwin Williams May 2006 March 2009 Wrote and supported software to prevent product recalls due to mislabeling. Several verified product recalls were prevented due to the software and the process was identified as a company best practice. Significant cost savings were attributed to the prevention of product recalls. Additionally, provided support for implementation at numerous facilities across the country. Designed and implemented a document management portal to centralize documentation within the facility. This project was featured in that year's Sherwin-Williams Company Yearbook, and created a foundation for future projects. Implemented devices from MOXA to situate all serial devices on the WLAN, which allowed for proactive handling of device errors. Problems were detected and fixed immediately, as opposed to the sometimes lengthy periods of downtime prior to the upgrade. The added value was the reduction in the possibility of product recalls as well as significantly reduced downtime - both contributing to cost savings.
