EXPERIENCE

GEOMETRIS LP HOUSTON, TEXAS-USA AUGUST 2009-PRESENT

Title: Embedded Software Engineer

Developed firmware for Vehicle tracking system using C language for the

LPC175x processor. Key contributor in interfacing this system with the GSM

modem and GPS module for over the air communication, protocol includes

SMS,TCP and UDP. Worked closely with the hardware team for best power

consuming product. Implemented very effective and stable supervisor(SiLAB

8051f334) system on existing embedded system.

In addition, worked with testing staff to decide test cases that also

includes drive-test of the system. Very confident in communicating with

customers directly and help them fixing firmware related issues or to

implement new features.

Tools: Silicon Lab IDE, Eclipse IDE with KEIL armcc compiler, FreeRTOS from

rtos.org, Rowley crossworks compiler.

ECUBE INDIA LTD, VADODARA, GUJRAT-INDIA JUNE 2006- DEC

2006

Title: Embedded firmware Engineer

Ecube India Ltd is an M-Commerce Technology solution provider company.

Worked as a junior engineer in writing, testing and debugging C code for

Access/attendance and vending machine system on 8051 microcontroller.

Duties also include device driver implementation of contact type and

contact less smart card with the application software which authenticate

the user and allow door access or vend the item in case of tea/coffee

vending machine system. Also developed device's LOG management system which

automatically sends the customer logs to the server every few minutes and

maintain the device memory space.

Tools: Keil C compiler for ATMEL controllers.

ASSOCIATE ELECTRONICS, VADODARA, GUJRAT -INDIA JAN 2005 -JUNE

2006

Title: Embedded Firmware Engineer

Contributed in firmware design for 3-phase motor drives on PIC8f4431.

Responsible for developing software routine in assembly language to

generate 3 phase PWM pulses with soft start and stop. Developed basic

drivers for serial E2PROM, RTC, text LCDs used in metering system.

Contributed to generation and maintenance of quality documentation such as

Product Specifications, Technical Specifications, Code Developer's

Guidelines.

In addition, worked with Hardware team for component selection and

preparing connection diagram.

Tools: CCS C compiler for PIC controllers, MPLAB ide, PIC

simulators/debuggers.

EDUCATION

. Master of Science in Electrical - December 2008

GPA - 3.75

University of Texas at Arlington, Arlington, Texas

. Bachelor of Engineering in Electronics & Communication - May 2005

S.V.I.T. Vasad, India.

RELEVANT COURSES

. Embedded Microcontroller, Advance embedded microcontroller, Advance

microprocessor design

. Wireless communication system, Digital communication system

. Digital Signal Processing, Digital Video coding, Digital Image

Processing

. Other subjects like Advance Electronics, CMOS mixed signal Design,

VHDL.

PROJECTS

. Device Control using PC commands: Control devices like LAMP

brightness, motor speed, and speaker tone using DMX512 communication

on PIC18f4431 controller. Communication protocols used are RS232,

DMX512. Write the commands on HyperTerminal and control the devices at

the other end of Microcontroller.

. Co-operative RTOS: C code for the 18F4520 controller that implements a

cooperative RTOS with support for semaphores, system timers, and

priority scheduling.

. 32bit microprocessor design: Designed 32 bit pipelined microprocessor

blocks starting from Instruction fetch, Instruction decode, fetch

operand, execution block and write back block.

. Cache memory design: Determine the best architecture for the 256 kb

cache including type (set-assoc or direct), nway (if set-assoc),

number of cache lines, block size, and write strategy (write-back or

write-through).Assumed that the DRAM data bus is limited to 64 bits in

width. The code was written in VC.

. Wireless Mesh Network with Ethernet bridge controller: Build hardware

and developsoftware for a wireless mesh network and controller. The

software developed includes a real-time operating system, device

driver, protocol stacks, and application layer software for a

controller and device nodes in ISM-band wireless mesh network. The

wireless network controller will bridge to an 802.3/Ethernet 10BASE-T

network with a HTTP interface.

. Design of Digital Communication system: Design of physical layer

simulation(using MATLAB) reference system for a digital communication

system, a fixed wireless local area network(WLAN). Design includes

BPSK modulation, Up sampling, channel coding at the transmitter side

and Down sampling, channel equalizer design (MLSE and MDD) at the

receiver side. Plot the Bit Error Rate and compare the performance of

the system.
