PROFESSIONAL SUMMARY

I am an embedded system design engineer with 2+ years experience in design, development, testing and implementation of embedded system products across various domains. Proficiency in variety of platforms and embedded system tools are my biggest assets. I am having a strong passion to learn new technologies and have applied my skills to develop innovative ideas into real world products to solve real world problems. I wish to say that if your product has performance constraints, limited memory resources, or tight timing, I'm the person you would want to team up with.

CORE COMPETENCIES

I am good at writing firmware for microcontrollers (8051/PIC/ARM7) in C, have a working knowledge of digital and analog sensor design, and would do well in the art of integrating both hardware and software. I am exposed to various debugging tools (Multimeter/DSO) which assisted me during difficult to find problems. And finally I do have an excellent written and verbal communication skill which assists me in conveying my idea to others with much more clarity.

Remote Operator Interface Terminal is a product that involves building an advanced interface control and monitor industrial machineries from a remote place within the factory floor. The machinery was at a distance of about 50m from the control panel. The customer approached us to redesign an existing control panel that has an older style keypad and character displays with modern Touchscreen user interface. The panel communicates with the machine through an RS232 interface in order to deliver the commands given by the user. The display is a LCD panel which shows several operator buttons. Upon a valid button press the MCU detects this and a corresponding command will be issued on the RS232 bus. RS232 communication happens at a baud rate of about 9600. For each RS232 command, a success/failure code will be acknowledged back. Irrespective of the command, the acknowledge packet consists of an 8-bit temperature value, that will be displayed on the screen. The control panel has a timeout period after which the panel goes to a locked state. The user has to unlock the panel using a secret 4-digit numerical code before proceeding with other operations.

Smart Attendance Machine is an RFID based Attendance System that can be used in an Office, Schools, and Colleges. It can handle up to a maximum of 1000 users and the device is designed such that it can be used for user entry only during set time intervals. When a user enters, he must have the card and when it is shown in proximity, the device captures the card details, the time of entry, shows this information on a Graphics LCD to the user and sends it wirelessly to a remote computer that has a Zigbee receiver unit which runs the attendance database software. Upon timeout, the device accepts no further entry and denies any further entry with a buzzer beep sound. The user entry time period can be setup using the matrix keypad after entering a valid admin password.
