Flextronics Software Systems, Software Engineer (Gurgaon, India)                                                June '04 - March '06

·         Responsible for development of a tool called CODREV, it is an extension in VIM editor using vim scripts, it provides support for new user commands, using these commands, a code reviewer can add his comments while having a look at the code in vim editor. Comments are stored in xml file format. This project was accomplished during the training period at Flextronics software systems.

·         Responsible for development of 6 modules of iGMLC (intelligent gateway mobile location center), in brief iGMLC is a mobile network component (Both 2G and 3G), which provides Location Services like person tracking, fleet management, where am I etc. Architecture of iGMLC is tier based; iGMLC is a component based distributed system. It actually consists of three tiers. In a brief description, it takes XML request (Location request) over http connection, parses the request, makes a java object and does all authentications and authorizations on the basis of subscriber’s profile stored in iGMLC database. It also performs privacy checks for subscribers, if everything passes then it sends the request to MAP engine using JMS. On the basis of XML request, MAP Engine communicates with HLR and MSC to get the location of subscriber over SS7 protocol. Since iGMLC returns location in form of latitude, longitude, so sometimes it needs to send request to SMLC for conversion purpose. After successful retrieval of the location it returns the location to LCS client over http itself.

Technically iGMLC was a full of different technical exposures like J2EE , App servers like Weblogic, Oracle Application Server, Tomcat, HP-UX, Shell scripting, testing tools like Junit, Cactus, C++, Oracle, Informix database.
