Cisco Systems, RTP (NSSTG) – Software Engineer (June 2008 – present)o Involved in Traffic Classifier architecture and designing test plans and test execution strategy.o Redesigned software switching data path of various ISG feature processing and provisioning for Layer 2 and Layer 3 packet switching to target scalability and reduction of memory footprint.o Redesigned Session Management traffic class component. o Improved existing Session Manager and Policy plane interactions per new traffic class architecture. o Worked on API interactions with PPP data plane codebase.Code Quality Maintenance & Technical Expertise (ISG)o Worked as ISG triage lead. Interacted extensively with test teams as well as customerso Point of contact for ISG software switching data plane, segment switching manager (SSM), and prepaid feature.o Involved in sustaining efforts for features such as idle-timeout, port bundle host key (PBHK), layer 4 redirect, accounting, traffic classification, and subscriber session related services.o Working knowledge of debugging router crash and core dumps using gdb, memory trouble shooting. o Used tools such as Doxygen for document control, Fanfare for automated testing and Clearcase forsource code control.

o Responsible for the Interface Management and Route management components in Forwarding Control Layer (FCL) application in IP router product. FCL is a multi-threaded middle-layer that relays OAM requests to the network processor. Responsibilities included architecture and development of IPv6 support, test automation in FCL. o Implemented uniform configurable tracing mechanism for all the protocol daemons.o Implemented standalone Perl utility to auto generate header files capturing all system characteristics as part of the build process.

o Worked on real time Embedded software development of Medical instruments. Experience with RTOS development environment.

White box, black box testing of the firmware code, informal/formal inspections, generation of softwaredesign documents (SDD), and system testing of medical instruments.

o Design and development of microcontroller based embedded systemso Writing device drivers for embedded protocols such as USB, I2C, RS232
