Experience working through the entire development cycle of two products from initial development to release.Over 12 years experience in implementing algorithms using C/C++ and Assembly.5+ years experience in the development of microcontroller/DSP based audio system.Strong RTOS concepts with excellent skills in real-time implementations on different microcontroller platforms.Experience in developing USB communication software, I2C and serial communication protocols.Experience in working with different microcontroller platforms including PIC, MSP430, ARM7 and Cortex-M3 architecture.Experience in the use of logic analyzers, oscilloscopes, signal generators for testing and debugging embedded system software.Initiated and encouraged the use of perforce version control software to maintain C/Assembly language code.M.S in Electrical Engineering with strong analytical, problem solving and good decision making skills.Effectively used tools like MSP-FET flash emulation tool, TI XDS510, J-Link emulators to design, implement and debug embedded software in C/Assembly languages.Added support for multiple phones and modems to be used for voice and data testing in the testing products.Implemented phone drivers interfacing.Developed driver code to implement downlink and uplink RLC throughputs and retransmissions, HS-DSCH sub frame error rate and block error rate, MAC layer throughput, modulation scheme and number of codes used in HSDPA, CQI, transfer block size and NACK rate.Implemented an alert detection code for GSM/UMTS. This keeps a running average of all the phone parameters and generates an audible alert and also displays on the screen when these averages cross certain thresholds.Developed application code to display the over-the-air (OTA) messages for GSM/UMTS and data testing parameters for UMTS/HSDPA on the screen.Used RTXC’s time based directives for synchronization of tasks with timed events for UMTS and HSDPA parameters.
