·   Selected to design and implement NSA compliance regulations and network design for all global customers on US soil.  I implemented regulatory policies for operations, service delivery, design, and support of customer infrastructure for US only management of hardware. This included building a global hub office with embedded management capable infrastructure requiring a network redesign of our core, moving and modifying equipment used to login, monitor, and store device configurations.  Bottom up security builds were required for protection of the new management network from global intrusion on several access points including Internet, MPLS, VPLS, and any possible incursion from our client base or parallel global teams.

·   As the current US network expert, I have been tasked with supporting implementation and network connectivity for our core backbone consisting of various MPLS, VPLS, and Internet ingress and egress access points.

Troubleshooting LAN networks that are past my obligated support level.  Advice and configuration examples for route redistribution from LAN to WAN, failover using GLBP or HSRP, PBR, load balancing via route map tagging in BGP or metric based specification.

·   I am called into customer network discussions involving complex routing issues that include identifying route injections through prefix overload and broadcasts, isolating issues with riverbed or similar optimization equipment, determining problems with call routing, packet inspection, etc. as the last level customer contact and I consistently deliver resolutions and mitigate any further escalations. 

·   Responsible for design, support, and operations of multiple global customers. The sizes of each vary from 25 sites to 400+ sites operating within the North & South America, Europe, Asia, and the Middle East.

·   Provide training and support for implementation engineers and network management center personnel.

·   Assisted in the successful implementation of multiple global projects consisting of 25 to 100+ sites each utilizing a variety of technologies such as MPLS, VPN, BGP, QoS, P2P, EIGRP, Cisco ASA, etc...

·   The position ensures the correct approach is used for all complex changes on the client network and to offer advice and support to ensure that they are implemented correctly.

·   The position offers advice for Network operation Level 3 engineers in understanding of a customer network to assist them with troubleshooting and ensure that they have the correct level of technical support documentation.

·   Required to carry out lab testing to support complex changes and testing of new design concepts for the client networks.

·   Supports the Account Sales Representative with technical detail of any complex change proposal to the client.

·   Responsible for approval of any complex change proposed.

·   I advise any Implementation engineer on the best approach for implementation of the change.

·   I ensure that the change engineer is aware of all technical documentation requiring updating as a result of the change.

·   For complex changes, I am required to implement the change.

·   In production networks, I will investigate faults deemed as ‘design faults’ to find a resolution.  This involves troubleshooting the fault and ensuring changes get raised to rectify the fault.  This will also involve in depth analysis with the client to find a resolution.

·   Responsible for working with the customer in workshops/meetings for in depth design discussions.
