Sr. Software Engineer

Primary projects:

Architected, designed, developed, tested, and deployed a CMTS Cable Modem Termination System Topology Application. The application captures customer modem MAC addresses and the associated CMTS physical port information by using Dynamic Load Balancing DLB technique, which allows the CMTS to manage connections to a cable modem based on bandwidth utilized at any given time and updates the Procera PSM Procera Subscriber Manager via a Web Service call with MAC addresses that have changed CMTS assignment or new MAC address that have not been previously notified to the PSM. This makes the Procera platform aware of which CMTS interface each modem/customer resides on and the capacity of each interface and therefore enables implementation of traffic policies and traffic shaping.

Architected, designed, developed, tested, and deployed an Enterprise Telephony Tools Query eTTQ Web Service to present diagnostics and troubleshooting information and functionality to support Tier 1 Residential Telephone Technical Support agents in assisting customers. Using eTTQ the TSR can quickly identify the source of the customer's trouble and perform troubleshooting steps in attempt to resolve the trouble without escalation to the next appropriate level. This Web Service is accessed by iNav users to query the switch and line level details for a particular telephone number. Lookup tables are built for getting device level details to use in polling. WebNMS built a polling framework on the central servers which will be accessed via RMI call.

Maintained and enhanced Node Combing Plan NCP and Cox Business Availability CBSA projects.
