Senior Engineer and Team Lead

Responsibilities:

• Team Lead supporting approximately 15 UC Coworkers responsible for managing the Enterprise Cisco Unified Communications network backbone that spans multiple Data Centers with complete network redundancy.
• Session Management Edition for centralized dial plan management and call routing
• Consistently evaluating technical and business process documents and modifying as necessary to meet the overall IT objectives set by Business Leaders.
• Evaluation of diagnostic tools used to maintain system integrity and functionality testing, both in lab and production environment.
• Currently leading the migration planning effort for the Enterprise Collaboration Portfolio from major release of Cisco System’s U.C. version 10.5 to version 11.5.
• This is a multi-team, multi-task effort, which also includes lab testing and verification to detail documentation producing Visio designs and test plan development.
• Successfully tested and developed the migration strategy for the tracking of Cisco Voice “End-Point Devices” Enterprise wide to meet Federal and State Government E911 regulations, using the current Cisco Emergency Responder Clusters for both the Backstage and Retail Cluster environment.
• This was a major shift from using the traditional “Switch port/MAC” based tracking to the new “IP Based Subnet” tracking so “Wireless End-Point Devices” can be “tracked live” during an emergency event. This feature now allows “Safety Responders and Emergency Personnel” to accurate track and respond to an area of distress without relying only on the caller. The migration strategy led to the development of new design standards. Standard based on square footage per ELIN/ERL association and the engagement of appropriate teams from cradle to grave for each new Site deployment and integration, led to overall time saving while meeting safety and legal requirements.
