Deskside Support Technician, Blue Water Federal, Falls Church, VA

At Defense Health Headquarters I performed deskside end user support servicing the 5000 member DHHQ staff, located both onsite and VPN connected remote. Diagnosed and resolved service incidents involving DHA computers running Windows 10/11 provided to DHA personnel. Tools used included Active Directory account modification, Bomgar representative console, ServiceNow ticketing and Powershell command line.

Systems Administrator, Leidos/SAIC Corporation, Falls Church, VA

Supporting test, integration, development and production environments for the Armed Forces Longitudinal Technology Application (AHLTA), the Theater Medical Information Program Joint (TMIP-J) and the DoD Healthcare Management System Modernization (DHMSM). Duties have included VMware vSphere virtual machine building, trouble shooting, STIG remediating, patching, and upgrading both Linux and Windows servers. Products maintained include Apache, Java, Oracle and Snareworks. Tools used include Nagios, MicroSoft Azure portal, Azure VDI, Consoleworks, Ghost, and ClearQuest.

2 years imaging, installing, trouble shooting, and repairing the windows OS laptop computers of the TMIP-J development and test environments.

Designed and implemented an upgrade to the TMIP-J software development LAN that introduced the bandwidth and processing efficiencies of data packet multicasting. This improved network performance decreasing Ghost server CPU load and time required to reimage multiple laptops simultaneously.

Produced $300,000 of annual savings for the DHMSM program by discontinuing the maintenance coverage of 500 VMware processor license keys purchased at DHMSM program initiation that I discovered had never been installed.

Specified, Installed and configured Zspace technologies suite of asset management tracking software that improved both the speed and accuracy of updating of AHLTA development GFE asset information by the introduction of a hand-held barcode scanner.

Configured data center network connected uninterruptable power supplies to initiate the transmission of Powershell controlled shutdown scripts on Windows operating system machines housed inside the TMIP-J climate-controlled room. Automatic operating system shutdowns prevented heat damage to GFE assets when running on battery power without climate control.

Specified, installed and configured Sensaphone data center environmental monitors to generate automated phone calls reporting alarms of high temperature, flooding or utility power failures.

Network Engineer, SAIC, Mclean, VA

Designing and testing network upgrades for the Long-Range Information Network Communications Services (LINCS) Program.

Produced a Detailed Design Document for network upgrades at nine buildings on Camp Pendleton supporting the 1st Marine Expeditionary Force. This document priced and explained in detail a design to cost effectively upgrade the digital connectivity of these facilities to make best use of a planned base wide installation of a Dense Wave Division Multiplexing fiber backbone.

Planned and performed laboratory interoperability testing of the Harris Secnet 54 with the General Dynamics Taclane Micro. This encryption technology testing simulated the bandwidth, delay, configuration, data type, and network load for the planned implementation of the Secnet 54 into the Mobile Suite being integrated into the United Kingdom Ministry of Defense infrastructure.

Planned and performed laboratory throughput testing and analysis of General Dynamics encryption technology and network accelerators from Comtech and Juniper Networks. The encryption testing generated a base line for fixed packet length impact on low bandwidth circuits. The accelerator testing discovered and documented a design flaw in Comtech’s latest version TurboIP firmware. This flaw caused unreliable processing of Common Internet File System (CIFS) packets that resulted in failed installations during the previous year.

Deployment Engineer, SAIC, Falls Church, VA

Designing and deploying network infrastructure and computers for the Composite Health Care System (CHCS) at DoD medical treatment facilities around the world.

Planned and performed numerous CHCS server upgrades throughout the United States, Europe and Asia.

Upgraded the hospital laboratory instrument managers that translate machine output RS232 into formats that can be input to CHCS, at numerous Army, Navy and Air Force medical centers. This project replaced obsolete DOS platforms with Data Innovations current software on windows platforms.

Conducted engineering analysis of transmission systems for CHCS communications upgrades. Used analysis results to generate proposals that specified the hardware, optical fiber plant and circuits required to replace obsolete equipment. These proposals were implemented at NAS Jacksonville, Cecil Field, Mayport, Scott AFB, Offutt AFB, Sheppard AFB and Travis AFB. At Jacksonville, Cecil Field, Mayport, Scott and Offutt supervised subcontractors installing equipment racks, fiber and LAN drops.

April 1989 to December 1994

Engineer, Computer Sciences Corporation

Systems Engineering Technical Assistance (SETA) engineer supporting the Federal

Emergency Management Agency (FEMA), and the Defense Manpower Data Center (DMDC). Also conducted performance testing of satellite transponder components and earth station TDMA modems at the U. S. Army's Integrated Test Facility at Fort Monmouth.
