ACADEMIC DETAILS:

Master of Science Electrical Engineering -The University of Texas at Arlington, Texas GPA: 3.5/4 (May 2017)

Bachelor of Engineering - Electrical & Electronics Engineering, India GPA: 7.84 /10 (June 2013)

RELATED COURSE WORK:

Embedded Microcontroller System Design, Microprocessors and Microcontrollers, Wireless Networks, Data Communication Engineering, Semiconductor devices, Digital Image Processing, Database Management.

TECHNICAL SKILLS:

Communication : SPI, I2C, UART, CAN

Language : C, C++, C#, Python

RTOS : FreeRTOS, Embedded Linux

Embedded IDE : CCS, Arduino, MPLAB, Keil, IAR Embedded

Protocol : HTTP, REST, MQTT, BLE, TCP/IP, UDP

Logic Simulator : Cisco Packet Tracer, Riverbed Modeler, MATLAB, Proteus

Cloud Experience : AWS, Azure

CI Tool : Team Foundation Server, Git

ACADEMIC PROJECTS:

IOT Home Automation Design: Implemented MQTT broker across Raspberry Pi 3 and Arduino. Pi senses the room environment, publishes the topic and Arduino node subscribed to the environment topic controls the relay of the home devices

(AWS IoT, Raspberry Pi, Arduino, MQTT)

BLE Application on CC2650: Implemented simple processor application using BLE. Interfaced CC2650 as Network processor and TI based board as Application processor. Set up one service with characteristic. Device connected to the Application processor is controller through mobile interface.

(CC2650, Tm4C123, Embedded C, GATT)

Real-time Operating System for M4F controller: Developed preemptive RTOS solution with the support of semaphores, sleep, priority and scheduling. Implemented single task function executing two tasks. Debugged and Analyzed execution timing using Tracealyzer tool

(STM32Fx, Embedded C, Keil, JTAG ICE, Tracealyzer)

Circular Queue Message Buffer: Implemented Ring buffer data structure with fifo policy for single process to single process. Buffer stores the data from hardware interrupt and a process fetches the data for further processing

(Arm m4, Embedded C, CCS)

Low Frequency Signal Generator and Scalar Network Analyzer: Designed a system capable of capturing analog signals and generated various waveforms using TM4C123GH6PM ARM based controller. Designed Single side PCB. Controller was programmed in embedded c using Code Composer Studio

(TI controller, Embedded C, CCS, schematic design)

CAN Driver Development: Implemented CAN 2.0A multimaster bus between two nodes using PIC controllers and external CAN controllers to sense external temperature. Implemented I2C for inter controller signaling and SPI bus for sensor interface

(Pic18f, Embedded C, MPLAB, PICkit SWD)

Garment Printer: Reverse engineered and developed a low-cost Garment Printer using a standard inkjet print head and open source image processing techniques. ARDUINO Mega was programmed to control XY stepper motors and firing pulses to the print head. NOR memory (SD) interfaced through SPI bus for input data.

(Atmel16, Arduino IDE, SPI, Raster Image processing)
