Worked as a system analyst for Content Delivery Network (CDN) organization implementing CRN application in the J2EE environment. The major component which is iDNS (intelligent DNS) is a special purpose DNS which provides intelligent routing for services through the DNS protocol and utilizing the real time network feeds including the BGP data. The J2EE client is GUI (CRPortal) as well as HTTP command line interface and the server is HTTP RESTful web services. The EJB component is implemented to authenticate the data between client/server in JSON format. The project is developed using Agile Software development with Scrum framework. Extensive experience in developing various tools including following.

·   Implemented Test Automation framework for J2EE client RESTful Web Service for CRUD (Create, Read, Update, Delete) operations in JSON format using client GUI (CRPortal) as well as direct HTTP request interface for the MYSQL server database. Apache Tomcat is used as a servlet container running the RESTful web services. Scripting implemented in C/UNIX/shell interfaces.

·   Manually tested AT&T network routers configuration by using HP Quality Center (v8.0) test management tool which is Application Life Cycle Management Tool (ALM) as it supports various phases of the software development life cycle.

·   Developed a Java (1.7) application (Server Capacity Tool) to update the number of cache servers located behind VIPs (Virtual IP Addresses) as reported in the network load feedback responses so those will be in sync with the CORA MySQL database as well as Oracle (PRO*C,PL/SQL) in UNIX/C environment.

·   Implemented/Tested Java (1.5) application (StatCollector) to collect and distribute the real time network topology data extracted from the ETL server to the respective entities. The XML parsing done by JAXB as well as DOM parser and errors reported using UNIC/C scripting.

·   Integration testing of IPV6 involving dual stack (IPv4/IPv6) CDN configuration for the CDN application using JAVA (1.7) with Eclipse (JUNO).

Senior Software Engineer

Working as a feature lead managing a team of 7 developers for implementing WIN (Wireless Intelligent Network) application for ISCP real time Telecommunication system for domestic as well as international customers.

·   Implemented Collaborative software application for Future Combat System (FCS) using IM Jabber client-server system involving Jabber/XMPP protocol on XCP Extensible Communication Platform with messages exchanged using chat/discussion repositories for the FCS personnel in the field for its middleware software system. Involved in developing on LINUX in C++ (object oriented) with the dynamic configuration of the software system by generating real time XML files from XSD schemas. The system is implemented with multi-threading (Pthreads) and ODBC interface.

·                                Implemented tools to feed real time configuration to the network application and verify the system behavior and generate the appropriate alerts.

·                                Tested SIP call flows as per the Call Control Server requirements for origination to termination of a call handling over VoIP network in case of Proxy SIP INVITE to the final receiving SIP phone. The INVITE of the call is sent via ISCP/portal GUI (SPACE) ISCP system. The call is passed through SIP Proxy servers/soft switches which is the interface between SIP network and ISCP/SPACE system. The parameters include no-answer timer, a session timer (for mid-call event processing), and request for call completion information.

·                                Coded a major part of the system using C++ as well as inspecting the implemented code by other team developers to ensure fault tolerant system.

·                                Perl/Awk scripting implemented to load the Enterprise mobility so the dynamic configuration for the new releases of the system is available on demand.

·   Designed and developed compiled services to improve the performance of the ISCP systems designed as COREINAP network application for Wireless/Mobile networks as per the ETSI protocol standards for the international clients. COREINAP application is the international version of the ISCP family of Intelligent Network Solutions. It utilizes the ETSI protocols.

·   Tested prepaid SMS SERVICES involving real time billing for the subscribers by collecting data using XML interface. In addition, solution testing of various IN solutions.

·   Performance analysis of the software system using Tprof and Pmapi code profiler.

·  Designed, implemented and coordinated the software development for the StrataCom Front End System capable of providing the Customer Network Management (CNMS) System the Frame Relay and ATM switches data including the PVCs, and Ports related to the Cisco/Stratacom IPX and Axis/BPX bases switches. Monitor the performance and the capacity of exclusive network resources (PVCs and Ports).
