About

I have 13+ years of experience (M.Tech + Industry) spanning from wireless networks, system modeling, embedded firmware/software development, and network protocol development. I have a sound understanding and exposure to WLAN PHY standards (IEEE 802.11 n/ac/ax/be) , IEEE 802.15.4 LoWPAN networks, TCP/IP protocol stack, L2/L3 (Switching/Routing) network protocol stack etc. I also have experience of developing software solutions using C/C++ for IoT devices and RTOS. I am inclined to build products and solutions from scratch. I have the ability and skillsets to take designs from concepts to implementation. I am a team player with strong communication and interpersonal skills. I have a Master's degree in Communication Engineering from IIT Bombay. I am at present working as a Staff Engineer - Software Design (Software Architecture Team) on WLAN IoT Product design and development.
