EXPERIENCES
2012 - 2019	NICEFIT, Hyderabad
	Technical Lead, Nicefit Innovations
	Nicefit Portal

2009 - 2012	EXFO, Bhubaneswar
	Principal Software Developer, Analyzer R&D
	iPro Server
	Designed and implemented iPro, a very high speed (10Gbps) network data capture and analyzer Linux server. Modified open-source Libpcap library to support multi-threaded access. It implemented a circular buffer and used spin lock. Optimized it for performance. All daemons of iPro were multi threaded. They communicated to their clients via TCP/IP, using special request/response packets. Most important concern was dead-lock freedom, since iPro was designed for high availability. + Alone designed and implemented 90% of the back end code of this product line.

	Senior Software Engineer, Mobile Devices
	DSP Data logger
	Implemented logger for DSPs of Motorola mobiles using Symbian C++. Logger collected data from DSP and sent it to PC via TCP/IP and SD card. + It increased productivity of developers by reducing debugging time spent on critical DSP related issues, as logs from DSP was readily available on PC for analysis.
	OpenGL Support for SVG Engine
	Integrated OpenGL APIs into SVG Engine of Motorola mobiles replacing its old software based algorithms. + It improved rendering performance greatly.
	GUI Library
