OBJECTIVE:

Seeking a challenging position where I may utilize my seventeen plus (17+) years of progressive and diversified experience in multiple areas and roles such as “Architecting, Design, Implementation, Installation, and Configuring” of complex Unified Communications Solutions. This includes but not limited to most of Cisco’s UC Port Folio such as Cisco Unified Call Manager clusters, Cisco Unity Voice Mail clusters, Cisco Jabber, Cisco On - Premise WebEx, and Cisco VCS-C and VSC-E “VPNless” solution. Over the course of seventeen years, this also included Maintenance and Operations of various Information and Communications Technology (ICT) Networks Globally, in various industries ranging from US Defense Department, to the Transpiration (Airline) industry.

PROFESSIONAL EXPERIENCE:,

Confidential,Houston,TX

Senior Architect

• Provide Architectural and Engineering leadership with strategic direction to Confidential Unified Communications (UC)/Voice Engineering and Operations Team within the IT Division. This includes direct involvement in the development of Enterprise IT policies, standards and guidelines that direct the selection, development, engineering and implementation of Unified Communications Technology Globally.
• Published and authored United Airline’s Unified Communications “Reference Architecture and Engineering Guide” on the EA Portal, jointly developed with the input from the U.C. Engineering and Operations Team based on the Cisco System U.C. version 10.5.2. This is a continuous process of improvement, with preliminary efforts underway to update the Guide based on version 12.0, meeting the business objectives of Confidential globally. The Design Guide also covers the “Enterprise Voice Strategy” covering multiple areas such as the Centralized Dial Plan and “Centralized vs. Distributed PSTN SIP Trunking” and where features such as TEHO and On-Net Dialing can be leveraged, which will lead to considerable savings in International toll charges.
• Actively led all group efforts with the U.C. Engineering team, with the selection of a spec’d based equivalent of a Cisco UCS Server platform in which the HP C7000 “Multi-Blade Chassis Server model” was identified, following the Enterprise Platforms Standards, and appropriately selecting the CPU type, sizing the RAM memory and hard drive with future growth capacity for U.C. application installs. All Cisco U.C. and “Voice Peripheral Application Servers” were migrated from physical to virtual servers, leveraging the VMware technology, in which all U.C Systems were evenly distributed across multiple HP C7000 Servers with redundancy designed and achieved via hardware and application software.
• Active participant and “co-lead” in Designing, Engineering and implementing the Enterprise Unified Communications (U.C) core infrastructure which is divided into four “functional units of growth” (cluster modules) based on the placement of the Cisco Unified Communications Manager clusters (with dedicated TFTP and MOH virtualized servers). These “cluster-modules” (developed on version 10.5.2) are segmented based on business units serving specific areas of the enterprise, and are referred to as the Enterprise Campus Cluster (ECC), Airport East and West Cluster, and the Network Operation Center (NOC) Cluster. Each “cluster-module” also includes the follow U.C suite of applications:
• Cisco Unified Communications Manager
• Unity Connection Centralized Voicemail System
• Cisco Unified Presence - IM&P (currently being tested and evaluated)
• Cisco VCSE/VCSC for VPN-less connection for Cisco Jabber (currently being tested and evaluated)
• Developed “Test-scripts” for both “technical and business used cases” and actively participated with all pre-check migration and acceptance testing for operational readiness with the U.C Team. This also included integration testing with the Unify Radio Console Turret System and the Genesys ACD system currently being used to route “internal customer, non-revenue ( Confidential Staff)” traffic for Departments such as HR, Employee Assistance Center, Pilot and Flight Attendant Help Desk etc.
• Developed and published the Engineering Standards Guide for U.C. Gateways based on the 4300/4400 ISR model series (following the WAN Transformation guidelines) for connectivity to the PSTN Network at Data Centers and remotes sites. Details on DSP resource calculations, and sizing with the appropriate selection of PVDM cards is also documented.
• Developed and documented the strategy to migrate all locations currently operating with legacy TDM PBX and Key systems to one of the four newly implemented “in-house” centralized Cisco VoIP clusters. This effort also includes the shutdown and retirement of the legacy Continental Airlines “centralized” Avaya TDM PBX System which serves as the “host” to approximately 128 remote sites connected via IP Trunks carrying “On-Net” voice traffic. This strategy is a multi-year design and implementation effort, with the goal to ultimately merge all major Cisco UC Clusters “Globally” via Cisco Session Management Edition (SME Clusters), saving on the overall OPEC, while bringing all maintenance under one Global Team.
• Key participant in a joint collaboration effort with the Enterprise WAN and U.C. Engineers to document the best practices and guidance leading towards a unified global MPLS network capable of transmitting both U.C. Voice and Video Conferencing Traffic. These studies are in preliminary stages where existing WAN circuits of remote sites and data centers operating over existing multiple MPLS Clouds are being evaluated for bandwidth optimizations, cost reductions, capacity planning, security vulnerability and the application of the “QoS” schema to optimize U.C. traffic. This is a multi-quarter effort which is currently in-progress.
• Perform technology assessments and reviews in order to score maturity, measure performance and recommend improvements that will lead to the next generation “OnNet” Global UC WAN Network which is currently being developed and planned for. This includes evaluating various Network Management System (NMS) Tools for monitoring the centralized Cisco UC Clusters, such as Prognosis and Cisco Prime Infrastructure for “Enterprise Voice” in which day-to-day operations, monitoring, provisioning and troubleshooting can be achieved. Examples of other UC Technologies also under review for future implementation include the following:
• Oracle ACME Packet Session Border Controller (SBC) vs. Cisco CUBE (Unified Border Element) for Distributed SIP Model deployment in Confidential . This is in early evaluation stages.
• Cisco Jabber with use cases using the Cisco VCS-C and VCS-E for VPN-less connectivity to the Confidential Corporate Cisco Telephony Network.
• Evaluation of Skype for Business: Integration with the Enterprise Campus Cluster as a Soft Phone solution.
• Evaluate advance features of Cisco Call Manager Express solution such as ACD call routing for CONUS and International sites that are not connected via the Global MPLS backbone.
• Analyzed audio conferencing & desktop sharing needs for the enterprise. It was determined as a Team to continue with the outsource model with AT&T WebEx and look at a possible in-house solution also based on Cisco WebEx at a later date. A full cost/benefit analysis was performed and presented.
• Assist in performing analysis and diagnosis of complex voice and data network issues related to Unified Communications.
