Accountable for network design, ordering and provisioning each site's circuit, BGP configuration and the configuration and installation of each router, switch, WAN optimization appliance, wireless LAN controller, access points, and wireless intrusion prevention system.

Responsible for the design, deployment and administration of fifteen virtual machines across four ESXi servers using VMware vSphere / vCenter 5. Managed and provisioned NetApp storage area network (SAN) providing networked storage via iSCSI for all systems and users. Enforce network security throughout all seven layers of the OSI model by: creating access control lists (ACLs) for Cisco network equipment; creating rules using McAfee Enterprise (Sidewinder) Firewall; filtering inbound/outbound HTTP/HTTPS traffic via Blue Coat proxy server; and configuring TACLANE KG-175Ds, a NSA Type 1 HAIPE network encryptor. Extensive troubleshooting experience using all the above systems.Provide classified and unclassified directory services for up to five hundred users in a forward deployed location within twenty four hours of deployment using a mobile communications suite. Demonstrated expertise in: the installation, configuration and administration of Windows Active directory and Microsoft Exchange; creating and managing users, roles, profiles, rights and permissions, organizational units, sites and group policies; adding and removing clients and servers from the Windows Domain; managing printer and file sharing services; troubleshooting a wide range of issues including DNS, Exchange, DHCP, LDAP and user permissions.Worked with the Air Force Research Lab (AFRL) and the US Marine Corps to test tunneling IPv6 over the military’s newest mobile communications equipment. Successfully passed IPv6 traffic over an IPSEC tunnel via satellite transmission to AFRL headquarters in New Jersey and accomplished the first IPv6 phone call during a DoD exercise.(Microsoft Active Directory, Exchange; Unix, Windows Server 2003/2008; VMware vSphere 5, vCenter Server, ESXi 5 hypervisor; McAfee Enterprise (Sidewinder) Firewall, ePolicy Orchestrator (ePO) 4.5; Blue Coat ProxySG 900; Cisco 3750, 2821; TACLANE Micro KG-175D; NetApp FAS2200; LDAP, DNS, DHCP, NTP, FTP, HTTP/HTTPS, SNMP, TCP, UDP, IP)

Designed, integrated and installed Department of State’s Threat Intel Fusion Center (TIFC), the first joint agency intelligence center in State Department history. Demonstrated expertise in audio/video distribution systems; remote, secure, fiber-based KVM solutions; video walls; video teleconferencing and unified communications equipment – all across multiple classification enclaves up to TS/SCI. Accountable for the engineering and installation of four tactical operation centers (TOCs) supporting various government agencies. Developed a wide range of skill sets and troubleshooting knowledge while on installations with strict timelines and minimal resources. The overall success of these missions earned our team recognition on the executive and congressional level.Conducted multiple site surveys evaluating existing C4I systems in hazardous environments. Participated in requirement elicitation and documentation facilitated through multiple design reviews with key project stakeholders translating requirements into design elements.Upgraded the wired and wireless network infrastructure for several major US military hospitals during operational hours with minimal downtime and zero impact to life safety. Evaluated end of life (EOL) equipment then proposed a cost-effective and scalable solution. If existing equipment was replaced with a different vendor, our team would train on-site staff how to operate and maintain a secure and efficient network; therefore, extensive technical knowledge of Cisco, Nortel, Brocade, Juniper and all network protocols is essential. A system operational verification test (SOVT) is performed after each integration and all results, including configuration files and wireless mappings, are provided to the customer.(Broad range of network routers, switches and edge devices: Juniper, Cisco, Brocade and Nortel; AMX; Crestron, Extron; Planar; Thinklogical, Raritan; BiAmp, Crown, ClearOne; Tandberg, Polycom; Citrix Thin Clients; TACLANE KG-175D)

Supported all aspects of FM Global's enterprise network infrastructure from Cisco routing and switching, WAN technologies and perimeter and firewall devices. Worked closely with the data networking team on a major migration project that involved upgrading the existing North American frame relay WAN to MPLS. The implementation of MPLS allowed our team to enable quality of service (QoS) and eliminated the traditional “hub and spoke” topology. Reduction in overhead, increased link efficiency, and the ability to prioritize time-sensitive data allowed the deployment of IP phones and video teleconferencing. Management estimated this project would save the company millions of dollars in telephone and travel expenses over the next decade.Responsible for the preparation of each branch site to support the MPLS migration. Installed and configured each Cisco aggregated services router (ASR), an all-in-one solution which increased network security while reducing the footprint. Created and implemented a baseline image to accommodate the increased voice and video traffic. Integrated Cisco Wide Area Application Service (WAAS) devices, a caching device that provided the existing WAN links the ability to support the increased network traffic without purchasing additional bandwidth.Day-to-day responsibilities included: routine network maintenance; performance monitoring using NetScout amd Nimsoft; wireless access point (AP) deployment and management; access control list (ACL) design and implementation; and a wide array of troubleshooting from user permissions to data center VLAN management.(Cisco ASA, WAAS, ASR 1005, 2851, 3750, 3845, 4500, 6500; Checkpoint Firewall; Nimsoft Network Monitoring, NetScout; RADIUS, TACACS+; MPLS, Frame Relay, HDLC, VTP, BGP4, OSPF, EIGRP, IGRP, RIP, IS-IS, TCP, UDP, DNS, SNMP, NTP, AAA)
