About

I develop firmware, drivers, libraries, and applications on the Linux Platform. I have done projects from scratch; as well as worked on enhancements to existing projects. ► Insight into software development in C/C++/Python, Socket Programming, Linux System Programming, and Linux Kernel Programming. ► Strong foundation in software engineering, data structure, operating systems, and embedded systems. ► I am currently working with Xilinx Inc. and develop software required for reference designs and proofs-of-concept of new FPGA Applications ► I worked with Qualcomm Inc. for almost 2 years in Android GPS Team and gained insight into board bring-ups, feature enhancements, and large-scale product development. ► I have a master's in Computer Engineering from prestigious NIT Jaipur; co-authored and published papers in IEEE; and presented the Network-on-Chip research at the University of Southampton, UK.
