Sr. Network ArchitectNorthside Hospital Jul 2017 - Jul 2020Atlanta, Ga, UsAct as the organization's most senior technical advisor providing technical expertise to set the vision and strategy for the use of any and all network technologies. Apply complex design principles and methodologies to ensure cost-effective and optimal use of Northside Hospital's resources and technology without jeopardizing network integrity. Present to and influence organizational leadership, colleagues, business partners and industry experts with the defined vision of the Northside Hospital enterprise.Developed and deployed Northside Hospital’s next generation data center strategy leveraging Nexus 7700 and Nexus 9000 in ACI network centric mode. Routing to and within the data center core was accomplished using OSPF, eBGP, iBGP with clustered route reflectors. A multi-vdc Nexus deployment provided ingress/egress route control points within each data center. An Active/Active data center strategy was envisioned and deployed leveraging a mixture of Network and Application Centric ACI and unicast OTV for data center load sharing over redundant 30Gbps diverse path backbones. Developed a Python and Ansible based application deployment model capable of deploying multi-tiered, multi-contract ACI based applications in one step. The application deployment model has reduced deployment time from 35+ minutes to under 3 minutes.Transformed the Northside Hospital WAN from a mixture of ATT L2 switched Ethernet, P2P, Virtual Packet Ring and SONET to a POP diversified MPLS eBGP based WAN. Championed the Citrix NetScaler SD-WAN initiative at Northside Hospital to lower overall hardware and WAN costs for our 150+ remote clinical offices while also providing multiple diverse paths and increased bandwidth and quality of experience. Remote office hardware costs were reduced by 300% and WAN connectivity costs reduced in some case by over 500-600%. This reduction in cost realized an R.O.I of just over 7 months and in many cases as low as 4-5 months when replacing Metro-E circuits. -

The role requires an expert knowledge of L2/L3 LAN and Multi-carrier WAN design, transport and troubleshooting in order to effectively deploy the technology. These customer activities require an expert and in-depth knowledge of today’s most pervasive routing protocols such as eBGP, iBGP, OSPF and EIGRP. Typical customer activities included but were not limited to Data Center core and multi-carrier WAN edge re-design and deployment, Branch office WAN re design and deployment. The role requires extreme agility in order to adapt to ever changing customer environments on a day-to-day and even hour-to-hour basis. Project management was key in order to maintain order across multiple customer design and install activities. -
Senior Manager - Global Voice And Data / Network ArchitectCeb, Now Gartner Jun 2013 - Sep 2015Arlington, Va, UsNetwork Architect and Senior Manager of the global voice and data group tasked with managing a multi-continent, multi-cultural group of Network and Voice engineers. Additionally tasked with the consolidation and restructuring of the CEB data centers, researching and designing future high performance network infrastructures, and the design and support for all global remote office communication systems.Developed and deployed a global network infrastructure for the CEB virtual private cloud with two data centers in the US, two UK data centers, as well as data centers in both Australia and China. The virtual private cloud data center infrastructure was based on Nexus 7009 and 7004 Multi-VDC core platforms, Nexus 56128, 5596, 5548, and 2200 access platforms and ASR1001 and 1002X WAN platforms. All data centers were interconnected via eBGP and iBGP using a global gigabit backbone with a multi-carrier MPLS edge infrastructure providing the utmost redundancy. The private cloud was built to accommodate and scale with multiple VBlock 700 and 300 series back end platforms. Each data center was deployed and operational in less than seven days, and in one case three days.Developed a standard CEB remote office template using Cisco2900 WAN Routers and Voice Gateways, Catalyst 3850 and Meraki cloud managed WAPs to ease deployments at remote site where adequate engineering availability may not be present. Removed all server, storage and security related hardware from the remote office by virtualizing all devices onto a Riverbed Steelhead Fusion solution reducing the overall remote office deployment cost by over 40K.Championed the consolidating of networking monitoring tool from a mix of various tools down to three core tools; Riverbed Cascade Profiler and SteelCentral Transaction Expert for single pane of glass NetFlow and transaction analysis as well as StatSeeker and Orion for interface and device monitoring. -
