Professional Experience

Comverse Inc., (formerly DGM&S), Mt. Laurel, NJ

Senior Software Engineer and Technical Lead, 3GPP Diameter Protocol and

Applications (2007-2014)

. Diameter SMS Online Charging Capability in LTE Network: Successfully led

a group of developers across 6 subsystems to implement the OCS Online

Charging capability for SMS in the LTE network.

. Established an effective project management system to manage the

development efforts and track the progress and completeness of each and

every stage of the development cycle. The project management system had

been highly recognized by the development managers and referred to other

technical leads as a model for other feature development projects.

. Diameter OCS Performance Benchmarking: Led the efforts on configuring the

essential test environment of Diameter Client and multi-node OCS Diameter

Server to facilitate the Diameter load testing and the Proof of Concept

(POC) activity of integrating the Oracle RAC to the Comverse BSS system,

and successfully achieved the benchmarking of the BSS system performance.

. Development of Diameter Dictionaries: Defined and implemented in XML the

3GPP standard and vendor-specific variants of Diameter Credit Control

Application Dictionaries. The accomplished projects included the 3GPP

32.299 Release 8/9 and 10 compliant Dictionaries, and the vendor specific

variants to support the interface to the Ericsson and Huawei GGSNs.

. Development of Diameter Service Logic Element (SLE): Designed and

implemented the Diameter SLE add-on modules to mediate the Diameter Ro

and Gy interface CCR/CCA AVPs to populate the Charging Factors for the

OCS online charging server. The success of the projects expanded the

capability of the Comverse-ONE to support the Diameter charging

capability for the 3GPP applications, including LTE IMS/SMS/PS (Flow

base), MMS and Voice call application. The SLEs were implemented in C++

and XML.

. Miscellaneous Diameter Projects: Developed Comverse ONE Diameter Charging

Interface documents for IMS, SMS, MMS applications. Designed and

implemented Diameter training courses for Project Management and Customer

Support engineers. Analyzed and provided solutions for customer reported

issues.

. Enhancement of Diameter Gateway Unit (DGU): Contributed the development

effort to the implementation of the DGU with the capability of run-time

dynamic configuration of the Peers and Routes to the Diameter Client and

the OCS Nodes.

Project Engineer, IVRU for BSS Prepaid Systems (1997-2006)

Responsible for design, implementation and training.

. IVRU Interface Modules: Designed and implemented the Intelligent

Peripheral platform IVRU interface modules to facilitate the IVR

functionality of the PPS using the Comverse MMU/MSU IVRU subsystems.

. Language Test Tool (LTT): Designed and implemented the IVRU LTT to enable

the Telephony User Interface language development group to independently

and effectively test the prompts and announcements of multiple languages

for the PPS system. Responsibility included the set-up of the LTT test

systems and conducted training sessions at both US and off-shore

facilities. Demonstrated the ability of working in a global environment.
