PROFESSIONAL EXPERIENCE:

Network Engineer Mgr.

Confidential, Sterling, Virginia

As the Confidential Network Engineer Mgr, I am primarily responsible for architecting, implementing, and operating Confidential enterprise and datacenter networks. The following are some notable achievements I performed and am performing. I was responsible for redesigning and simplifying the WAN connectivity between all of Confidential 's enterprise locations both domestically and internationally. This consisted of scaling down the number of MPLS providers we were utilizing to two, which all of our domestic locations were homed to with ingress/egress to the internet thru one of two internet gateways, one located on the east coast for our east coast locations, and another on the west coast for west coast locations (with failover to each other). I designed, for each location, a method of load sharing traffic over both MPLS providers using a combination of OSPF and GLBP to gain full use of both providers, rather than an active / standby design. By simplifying our internet ingress/egress down to two locations, Confidential was able to save costs on DIA circuits as well as security infrastructure due to these security stacks needing to be deployed only at the internet gateways, and not having a security stack at each individual location.

I also was responsible for designing and implementing a dual hub single dmvpn cloud environment for which our international locations would use for connectivity back to the US. I was also responsible for researching, and choosing a NMS / Netflow solution that could be used to better understand and troubleshoot issues within Confidential . I deployed a solution using LiveAction coupled with AVC and Medianet flow capability which provided our NOC with better transparently into traffic flow and allowed them to view traffic on a per flow basis such as server response time, client response time, network response time, as well as packet loss, delay, and jitter for voice and video traffic. I was also responsible for standardizing network infrastructure and documenting it so that junior level engineers could quickly turn up new locations. I also played a key role in architecting a fully virtual datacenter (vRouter, vfirewalls, vloadbalancer) over-layed on top of a Arista vxlan leaf/spine infrastructure and because of this Confidential was able to roll out our first completely virtualized datacenter which consisted of only physical switches, ESX hosts, and flash storage arrays. This created a tremendous cost savings opportunity on power, space, and cooling and we were able to scale down a 30 rack datacenter to 4 racks.

I am also highly involved in the many acquisitions Confidential made and migrating these acquisitions into the Confidential network infrastructure. I am also responsible for tasks such as performing root cause analysis on revenue impacting outages and presenting findings as well as recommendations to Confidential ’s senior leadership.

Network Architect/Manager

Confidential, Fairfax, Virginia

As the Network Architect at Confidential, I am responsible for supporting a federal contract with Confidential. Confidential is a premier provider of web service and system hosting and provides a highly secure, certified, and accredited infrastructure to other federal government agencies.

In supporting Confidential and their internet data center environment, I’ve designed and migrated their environment to a fully functional dual- stack ipv4/ipv6 network and because of this, Confidential was one of a few hundred organizations worldwide which was able to participate in World IPv6 Day. In addition I redesigned the network architecture to include a ‘firewall sandwich’ topology which included several layers of firewalls that separated Confidential ’s Trusted, Untrusted, and customer hosted environments and eliminated single points of failure. As another layer of security, I was responsible for bringing the organization to TIC compliance as mandated by the US Office of Management and Budget (OMB), which included transitioning Confidential ’s multiple ISP’s to a MTIP service provider as well as deploying DNSSEC for all domains registered to Confidential .

I also, provided key support in building a NOC for better troubleshooting and response to network/customer issues, as well as documented via Visio and set up SNMP monitoring for Confidential ’s entire network as well as automated backups of all network infrastructure via RANCID. I’m also responsible for technical refresh with regards to the network infrastructure, as well as researching new network technologies. I am responsible for the management and technical leadership of a junior network engineer as well. The datacenter is a multi- vendor environment comprising of Cisco routers, switches, firewalls, and load balancers. Confidential load-balancers. Juniper Net-Screen Firewalls, as well as Redline load balancers. The datacenter utilizes the following routing protocols to provide the needed connectivity, BGP over multi-homed connections to the ISP, OSPF within the Cisco Catalyst core, and EIGRP within several of the larger segmented network environments. Other protocols implemented into the network are HSRP, sourced based PBR, DMVPN, IPSEC, multi-link ppp, as well as dhcp snooping into the enterprise environment.

Senior Voice/Network Engineer

Confidential is a hosted VoIP provider providing both voice and network services to enterprise customers in the Washington DC area. As the Senior Voice/Network Engineer, I report directly to the Chief Technology Officer (CTO) of the company and am responsible for managing and developing the core backbone, the voice over IP (VoIP) infrastructure, along with corporate products and services. My primary responsibilities are the design, configuration, and maintenance of the core voice infrastructure which includes management of our two BroadSoft M6 VoIP softswitch systems, as well as management of SBC’s, PRI gateways, and our upstream SIP termination and origination providers. I also provide engineering support on tier III IP routing and voice issues to our customer support engineers. In addition, I work closely with our resident CCIE on the MPLS interconnected core with maintenance and expansion issues and have a high working knowledge of VPNv4 / VRF routing. I also working closely with our customer implementation engineers on advanced enterprise level customer solutions/designs which require a great working knowledge of failover techniques as well as redundancy solutions.

Other responsibilities include helping to establish a corporate IP routing policy, working closely with vendors and suppliers and ensuring interoperability test have been completed, as well as providing high quality documentation of our core network and voice infrastructure. Key achievements at iCore were building out the companies second VoIP PoP from the ground up and well as bringing new hosted products we could offer our customer base such as call recording and

ACD monitoring. In the time I have spent as the senior voice / network engineer the company has doubled its customer user count from 15,000 to over 30,000 and I have played a key role in making sure the core network has kept pace.
