TCP/IP networking experience with protocol design and implementation skills on IP routing/switching systems. Detailed understanding of system design and implementation across the different layers of the OSI network stack and the MPLS stack. Track record of contributing to multiple product release cycles of the JUNOS routing software and Cisco Catalyst 6500 switching software. Extensive C programming experience on UNIX and its variants, and moderate familiarity with C++ Object Oriented design methodologies. Strengths: MPLS protocol suite, Ethernet and Layer 2 protocols, Unicast and Multicast routing, Layer 2, Layer3 and Multicast forwarding, C, C++.

Routing Protocols Software Engineer @ Individual contributor in the JUNOS routing team developing protocols features for MPLS/RSVP Traffic Engineering, RSVP fast reroute and path protection mechanisms, MPLS OAM for Point-Point and Point-MultiPoint LSPs From July 2009 to Present (6 years 6 months) Communications Server Software Engineer @ Individual contributor in communications server team developing Citrix Online's next generation servers for multi-core platforms. • Performance profiled Citrix Online's voice conference bridge to examine session join delay, session response, system load and other key system performance indicators. • Designed and developed a statistics module to collect session, jitter and system statistics and to monitor the performance of conference bridges in live deployment environments. From January 2008 to June 2009 (1 year 6 months) Santa Barbara, California AreaWireless Networking Research Intern @ Contributed towards driving “Tactical Airborne Ad hoc” networks as a new business area for UtopiaCompression. Prototyped a network topology maintenance solution for mobile airborne ad hoc wireless networks. Developed a topology aware routing protocol that exploited the unique characteristics of airborne networks. Implemented and evaluated the routing protocol on the Qualnet wireless simulation platform. This research work was published at MILCOM 2008. From June 2007 to September 2007 (4 months) Wireless Networking Research Assistant @ Developed SPEAR, a crosslayer networking stack for dynamic spectrum wireless networks. SPEAR consists of a spectrum adaptive routing protocol, a time interval based spectrum reservation strategy and a time division multiplexed multi-channel MAC protocol. It can be used in a variety of spectrum environments, either diverse or constrained, to better exploit the spectrum diversity than 802.11 systems do. Implemented and evaluated SPEAR on the Qualnet wireless simulation platform. Published research paper at CROWNCOM 2008. From 2005 to 2007 (2 years) Santa Barbara, California AreaSoftware Engineer @ Developed a protocol and performance test tool for Greenfield's Packetry Ethernet reference design system. Demonstrated Greenfield’s Packetry chipsets’ performance at customer locations using the above mentioned performance tool. From May 2004 to August 2004 (4 months) Software Engineer @ - Developed and maintained Port Security and 802.1x for CatOS. - Implemented Bidirectional PIM forwarding for CatOS From 2000 to 2004 (4 years)
