Professional Experience:
Rogers Electric
Lead Network/Security Architect
Mar 17 – Current
As an IT leader within the organization I am responsible for shifting the culture and maturing the mindset of the IT staff to plan, design and architect solutions that encompass current technologies that are scalable both on-prem and in the cloud. I have overseen the implementation of software defined storage (Cisco Hyperflex) to support our VDI environment, NETAPP to upgrade VNX storage, NSX software defined security, Cisco 9k data center 10GBPS backbone core, Telepresence as well as upgraded current infrastructure like CUCM and router refresh. I have begun to implement a contact center solution for our IT service desk as well as our customer support center utilizing SalesForce and New Voice Media. I established an Azure cloud presence with Office 365 as well as created an environment for a mobile app, federated AD services and BMC relay. I architected a network redesign to move away from MPLS to Cisco VIptela SD WAN for our sixteen office locations utilizing a mixture of DIA circuits as well as broadband. Additionally we are currently designing a disaster recovery platform to be housed in a private cloud that will seamlessly fail over at the start of our runbook utilizing the new SD WAN infrastructure.
Family Dollar, Matthews, NC
Sr. Network Engineer/Architect
Feb 15 – Feb 17
I lead all technical initiatives related to the day-to-day communication and integration between Family Dollar and Dollar Tree. Worked closely and directly with senior management from both banners I created and manage new processes to streamline the design and implementation of all firewall and network requirements for necessary user and server/application access between the two companies. Quantitatively this created a time savings of four to seven days for each requirement from the initial request until implementation. Additionally, as a corporate cost savings initiative I introduced and implemented video conferencing to Family Dollar using Cisco MX300 video units. This allowed for face to face meetings at a cost savings of almost $5k per meeting when the corporate jets are not necessary for travel to meetings. This initiative paid for itself after only four meetings and continue to saves the corporation as much as a half million dollars annually.
For banner specific projects I managed F5 (GTM, LTM), routing, switching and firewall infrastructures from architecture to implementation. This includes building infrastructure in Amazon for cloud services and moving “on prem” services into the cloud.
Windstream Communications, Greenville, SC
Network Engineer III
May 12 – Dec 14
I managed several large-scale projects while working on a team designed to integrate networks into the Windstream AS. Our daily tasks include designing necessary network related changes to convert purchased networks into the Windstream AS. As a part of that process we determined the least impactful approach to converting IGP, BGP, as well as network standards. We created all change control documents used to perform network related changes during the maintenance period personally completing all configuration changes.
