Intrado, Inc., Senior Software Developer 8/2004 – 3/2011

Illinois team lead on selective router to route 911 calls based on location to call centers. Mission critical 24x7 applications developed on BEA SIP Server 3.1 on Redhat Linux platform to convert analog 911 calls to SIP/RTP as replacement for legacy phone switches. System was large-scale AGILE J2EE development. Technologies used: SIP, RTP, Java 1.4.2, Java 5.0, Oracle, PL/SQL, Spring, Ibatis, ant, maven, Subversion, Cruise Control, Continuum and Oracle access layer.

Developed embedded application on SheevaPlug platform (plug form factor with Linux on ARM processor) to monitor switch settings and control leds and output pins via SIP messaging. Used in emergency call centers to signal and set abandonment state to/from remote emergency router. Application had embedded web server implemented using Spring MVC via Jety. Developed installation software for installing kernel, root, and application for factory setup.

Developed Java-based network simulation/load generation system with front-end Groovy language scripting interface. System generated complex SIP and HTTP (REST) message flows for unit and automated testing. REST flow implemented with JAXB object bindings. Client-side HTTP interface implemented via Apache HTTP client. Server-side HTTP interface implemented with embedded Jetty web server. SIP interface implemented via JAIN-SIP. Developed Spring MVC front-end web interface for configuration and monitoring of generated message flows. Also developed prototypes of above system using front-end scripting in JRuby and Jython (as well as proprietary scripting via javacc).

Developed Tanuki-based Java application to do continuous monitoring of software components and network elements of 911 call router complex. Work involved scheduling multiple jobs via Quartz scheduler to generate test calls, ping network elements, test network connectivity as well as specific tests of application software functionality. Alarming via SNMP traps. RMI interface to allow configuration and manual triggering of tests via web portal. Technologies: Quartz, Ibatis, Spring (AOP and IOC), SIP (Jain-SIP)

Developed Windows-based 911 softphone client prototype for 911 VOIP calls. Work was done using Java 5.0 with JMF (RTP), Jain-SIP and Spring libraries.

Development on JSP Web application under BEA Web Logic Express 9.0 to do provisioning via customized Spring MVC controllers with data access layer provided by Ibatis to Oracle (11g) database.

Worked on feature development for Mobile Positioning Center (MPC) and Gateway Mobile Location Center (GMLC) to supply location information on 911 calls originating from cell phone. C development Using SS7 (ANSI and GSM), ASN.1 on Compaq Unix Platform. Ported software to Solaris Platform. Did comparative analysis of commercial SS7 stacks that led to selection of stack for this port.

Comnet International, Senior Software Architect 8/2001 – 8/2004

Software architect and lead developer(C/C++/VB/Java/Perl). Provided technical analysis, design and feasibility studies and recommendations on proposed software systems for the company. Lead developer on the following specific projects:

• Java client/server enterprise-wide system used to maintain network topology information. Used SNMP, JDBC, MySQL, Crystal Reports, JSP servlets under Tomcat. Client GUI implemented via Swing.

• JSP-based client/server system for provisioning telecommunications services. Project consisted of a Linux-based server components plus development on an PPC860 embedded system. Server components used JSP, Struts MVC and JDBC and communicated with embedded system via XML (SAX XML classes) over UDP. Embedded system development involved X.25 stack running on top of synchronous RS232 connection to a phone switch.

• Lead developer for enterprise-wide telecommunications system to deliver HTML-based calling party information to client PCs. Project involved VB applet on clients and server development under Unix/C with Oracle 8i. Client/server communication via UDP sockets.

• Specialized protocol converter devices based on Motorola PPC hardware platform. System uses TCP/IP, ISDN (Q.931), X.25 and SNMP and HTTP protocols and was developed using C/C++ under VxWorks (20K NCSL). Headed team consisted of 12 developers.(10 based in India, 2 locally).

• Developed from scratch web server in C on embedded platform to allow provisioned and monitoring.

• Developed inventory system using Perl to control software licensing that collected customer information into database and provided unlocking keys to track product sales.
