• Analyzes information through data models and architecture diagrams• Communicates the value of new IT strategies and keeps stakeholders informed of ongoing initiatives• Defines a best-fit solution for existing problems

Completed repairs, upgrades, and migrations on field site, campus, and data center network infrastructure. Collaborated with system administrators, engineers, and application owners to perform fault isolation and provide customized resolutions to network performance issues.• Designed virtual solution using VRFs to consolidate environment with multiple hardware stacks into one physical infrastructure, simplifying topology and cutting down ongoing administrative overhead and maintenance.• Minimized implementation service interruptions and eliminated design specification for separate hardware stacks by integrating routed network design into existing layer 2 topology utilizing transit VLANs for EIGRP peering.• Deployed Policy Based Routing (PBR) to forward backup and replication traffic over alternate / secondary WAN link, reducing circuit congestion and improving application performance over WAN.• Decreased mean time to deployment for future business projects by automating repetitive tasks, delivering single point provisioning, and allowing automatic fabric deployment with data center migration to Cisco Application Centric Infrastructure (ACI).

Provided Tier 3 network support and issue management of WAN perimeter and data center networks. Optimized WAN infrastructure between data centers and primary health care sites. Migrated legacy Nexus environment in the data center to Cisco ACI (Cisco Application Centric Infrastructure). Configured and maintained IPSec VPN LAN to LAN tunnels firewalls to control remote access to SCL Health resources.• Developed route-policy standards based upon optimal forwarding and constructed route-maps, enforcing policy on WAN routers achieving greater speed, resiliency, and high availability of critical business applications.• Transitioned data center DMZ and Internet Edge workload to Cisco ACI, simplifying design, and standardizing connections between data center core infrastructure and perimeter security resources.• Extended Layer 2 adjacency between data centers for DR continuity project with Cisco Overlay Transport Virtualization (OTV), delivering workload mobility between data centers.• Migrated 15 Microsoft DHCP servers to Infoblox, allowing IP address tracking and management of DHCP services from unified console reducing management overhead of core DDI services.

Identified and repaired network connectivity issues. Performed proactive diagnostic monitoring to locate potential network issues. Developed network policy standards, best practices, and managed hardware support to protect network integrity and comply with management directives regarding network performance.• Improved availability of critical Internet-facing applications for clients by deploying both BGP multi-homing on company Internet edge and cloud-based Neustar UltraDNS authoritative DNS.• Created and implemented a network for a new disaster recovery site and met business continuity objectives by mitigating potential downtime for critical business applications.o Project tasks included: itemizing critical network components and impact of failure, recovery test objectives, automating site recovery workflows, and Re-IP rules.• Determined and remediated cause of intermittent service interruptions on Campus LAN, developing NTP and Syslog policies and devising standards for centralized Syslog collection on Linux servers enabling event correlation of system logs from all network devices.• Completed network audit, provided specifications for a hardware refresh, and developed plan for LAN upgrade, addressing network performance concerns of business owners after a re-architecture and roll-out of critical financial trading applications.• Enhanced customer experience with critical business applications, configuring layer 7 inspection, and session persistence on load balancers, allowing customers to restore sessions and access cached information on application servers where they last connected.Systems Administrator Setup, maintained, and provided support for enterprise Linux, Unix, and Windows servers. Administered Active Directory, Exchange, Sendmail, and PaperWise imaging systems. Deployed SFTP and FTP/TLS on Linux servers for secure file transfer to external clients. Automated tasks with Perl.
