Work Experience
Information Sciences Institute, Marina Del Rey (Graduate Student Researcher) Jan 2015 - Present
 Contributing in developing a malware detection system in embedded systems (Embedded Linux, U-Boot)
Lister Technologies, India (Software Engineer) July 2011 - June 2013
 Responsible for design and development of SaaS (Software as a Service) based E-Commerce platform
 Automated processes and designed developer’s kit to help other co-worker’s
Academic Projects
Software IP Router in user space (C, C++ 11, Sockets, Pcap, POSIX Threads, Linux Kernel)
 Developed a user space IP router to dynamically update routing tables using custom OSPF
 Updated kernel routing tables using the user space routing table and supported packet destination unreachable scenarios
 Interfaced with quagga routers to dynamically update their routing tables as well.
Content Centric Network using SDN (C, C++ 11, Python, Sockets, POSIX Threads, Linux Kernel)
 Designed a Publisher-Subscriber model to share data among nodes and forwarded packets based on keywords/unique Id
 Dynamically installed forwarding rules for each subscribed keyword
TCP state machines on Open vSwitch (C, Python, Mininet)
 Modified Openflow protocol - Added support to match-action based on TCP flags
 Used multi-table capability in OVS to implement TCP state machines and added 5-tuple hashing to identify flows
Fast and Reliable File Transfer Protocol over UDP (C, Sockets, TCP/IP, UDP, SCP, POSIX Threads)
 Used UDP sockets to replicate TCP reliability to transfer file with higher throughput
 Achieved 92 Mbps for lossless link and 55Mbps for 200ms RTT and 20% lossy link over 100Mbps bandwidth link
Improving TCP performance over lossy links (C, Linux, SCP, TCP, Linux Kernel)
 Hacked into Linux Kernel to improve/remove TCP components including slow start and exponential back-off
 Achieved 16 Mbps throughput for 200ms RTT and 20% lossy link over 100 Mbps bandwidth link
Grid Computing Network (Java, Sockets, RMI library, Thread Library)
 Engineered a grid network to distribute processor intensive jobs among multiple executors
 Designed a centralized controller to coordinate, detect (least busy node) and delegate tasks among the executors
Designed a Custom Network Protocol (C, C++11, Raw sockets, POSIX threads)
 Minimized packet header length by stripping off Ethernet and IP headers to reduce overhead
 Added capability to support variable packet length and tested the protocol using our custom router
File Sharing Network (C, TCP/IP, Sockets)
 Simulated a resource discovery/ file – sharing network using hybrid architecture with TCP & UDP sockets.
Emulated Token Bucket Filter (C, POSIX Threads)
 Designed a time driven token bucket filter to transmit packets from one queue to another
