·   Provided remote and on-site support to major telecom service providers throughout the North America region for IP Multimedia System (IMS) and LTE systems.

·   As a recognized subject matter expert, reproduced and verified fixes for complex field issues in live IMS networks.

·   Resolved issues in live sites and customer labs - issues dealing with software upgrades, field installation, call processing, and networking. 

·   Provided outage resolution, root cause analysis, problem reproduction and fix verification.

·   Provided scripts to analyze large sets of log files and data to diagnose problems and pinpoint the issues.

·   Products supported include IMS Session controller, Application Servers, and Home Subscriber Services (5450 ISC, 5420 CTS, 5420 SCG, and HSS).

 

Ø       Project Leader/Feature Engineer/Software Developer (3/2001 – 4/2007):

·   IMS & UMTS-MSC Fault Recovery & Field Debugging

·   Designed and developed IMS Border Control Function (IBCF) using a SIP B2BUA.

·   Designed and developed a Client/Server application to provide QOS support in IMS.  Developed Go (3GPP), and COPS-PR (IETF) interfaces from scratch for Policy Deployment Function in the IMS architecture.  With field installation, proved that the developed stack is fully standards compliant.

·   Enhanced Open Source Diameter stack to develop a Client/Server application that provides Cx interface for IMS application on Lucent Control Platform (LCP).  In the process, resolved several thread synchronization issues in the open source stack, and stabilized it to run on a multiprocessor environment.  Defined the requirements for developing an in-house Diameter stack.
