• SharePoint Platform
Redesigned intranet websites to address the demand for a document repository, individual resource matrix, and ticketing system while aligning to record retention policies, which increased employee usage to over 80 percent.
• SQL Query Generation
Triaged client escalations by means of data extraction with Toad for Oracle software. This allowed to review and correct client account configurations, discrepancies in batch submissions, and duplicate transaction charges.
• Standard Operating Procedure (SOP)
Developed department standard operating procedures that improved incident resolution service levels and minimized demand hours when training new team members by 38 percent.
• Strategic Alliance
Built partnerships between cross-segment stakeholders by leveraging collaboration which expedited resolution of client impacts, increased the culture of open communication, knowledge sharing, and fostered feedback across multiple teams.
• Root Cause Analysis (RCA)
Facilitated triage meetings to address client impacts this, in turn, decreased the time to administer remediation, execute preventive measures, and update detailed documentation of each phase.

Governed business policy compliance and delivered horizontal support.

• Risk Data Analytics
Conducted weekly risk data analytics for security projects, to adjust user accessibility within the division’s identity and access management programs, in order to maintain compliance with yearly audit policies.
• Reporting
Presented updates of KPIs, RAG status, and metrics on the Monthly Business Report in PowerPoint to the department’s executive director and other company functional leads.
• Risk and Control Self-Assessment (RCSA)

• Audits
Engaged in semi-annual network audits through the presentation of network topology, rule-based analyses, system logs, and policies; thereafter initiated and delegated numerous action plans to address any audit-identified issues.
• Data Center
Voluntarily drove the decommissioning phase of a Data Center Relocation project. Objectives included procuring resources, capacity management, dismounting/recycling of cabinets and equipment, destruction of hard disks, shutting down carrier connectivity services, etc. Project completed months prior to the assigned deadline and under budget by approximately 20 percent.
• Resiliency Data Management System (RDMS)
Consistent data revisions, helped improve resiliency of the network recovery plan.

Managed the client network solution designs, connectivity support processes, initial configurations, and 24/7 global customer support.

• Network Connectivity
Configured access controls, VLANs, IPSec, Point-to-Point Tunneling Protocol (PPTP), Hot Standby Router Protocol (HRSP), Multiprotocol Label Switching (MPLS) on client routers and VPNs to ensured secure data flow to client networks.
• Switch Upgrade
Volunteered on an out-of-state switch upgrade project to install fiber optic cabling, mount/configure Cisco Nexus switches, test device functionality, and decommission preexisting equipment.
• F5 LTM
Monitored pools and nodes performance to determine what network resources needed maintenance or reconfiguration.
• Enterprise Password Vault (EPV)
Utilized tool to maintain segregation of duties, provide privileged access rights, and implement break glass strategies, this assisted in sustaining network security and upholding business compliance objectives.
• IT Service Management (ITSM)
Managed high-priority incident assignments and resolved network configuration change requests.
• Sniffer Tools
Analyzed data packets to troubleshoot network traffic flow and access issues, using Wireshark and Omnipeek tools.

Accountable for the day-to-day management of access controls and system maintenance across corporate services and resources.

• Access Control
Implemented RSA SecurID solution for Multi-Factor Authentication (MFA), decommissioned stale user accounts, security groups, group policy objects and enforced privileged access on service accounts within a PCI compliant Server Active Directory environment spanning multiple domains.
• Server Maintenance
Performed diagnostics, patching, backups, and upgrades across Windows 2000-2008 server platforms to ensure alignment with organizational standards and strategic business plan.
• Service Support
Managed day-to-day operations and monitored mission-critical services 24x7 related to Active Directory, DNS, DHCP, IIS, and internally developed application
