Programmer Analyst

Confidential

Responsibilities:

• As a programmer analyst, responsible for the design and development of the following for a security computing device:
• Remote software upgrade process (U.S.patent pending) will allow the device to check for any software updates and upgrade itself automatically to the latest software. It also provides the flexibility for the user to either upgrade the device or skip the upgrade altogether.
• Composite USB Mass storage and HID Driver is a Linux kernel device driver to mount the USB device as a mass storage as well as the HID device. The HID channel is used to communicate between the Linux and Windows applications.
• In addition to the above, also developed the user space linux inter process communication applications using socket programming.

Tools: Embedded C, Linux, Socket programming, Lua, Google Protocol Buffers APIs

Software Consultant

Confidential, Boca Raton

Responsibilities:

• The project is related to access control system used by organizations big and small which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. The device consists of card readers to extract data, an IO board which acquires the badge data and sends to the Main Panel for taking the appropriate actions based on the credentials. This also supports the configurable users (max up to 500K users), No. of Doors and No. of Authorities at system level (with per user allowing maximum up to 128). It also supports the various card formats like weigand (26/36 Bits), magstripe. AntiPass Back detection, arming the system, remote configuration are some of the key features. As a part of remote configuring the system, Google Protocol buffer APIs mechanism is incorporated as the communication media between the Main panel and the third party software’s.

Project Leader

Confidential

Responsibilities:

• FRS is a fault recording, synchronized phasor, fault location, power quality assessment and sequence of event monitoring device with remote terminal capability communicating with complementary integrated master station oriented towards the power system distribution market. It consists of Mother board with DSP,FPGA & POWER PC for handling all the functionalities of FRS. DSP &FPGA will be used for data capturing and sending the data to the CPU. The CPU functionality includes the data capture & recording from DSP & FPGA, storage & retrieval on request from the Master station or 3rd party devices.CPU is responsible for maintaining the user configuration & running the FRS with that configuration. In addition to record maintenance CPU is also responsible for Non-volatile memory management, event logging, accepting the triggers from remote entities (including cross triggers from other FRS units), auto-communication & MMI functionalities of FRS.

Tools: Embedded C, VxWorks

Sr.Software Engineer (Design and Development)

Confidential

Responsibilities:

• As a Project Leader initiated design and development of (i.e., modern digital hardware and associated software, involving fast sampling rates needed for Radar signal processing) Digital Receiver as an up gradation for the existing RTDAP of DWR Mark-I with the latest technology. This system is designed and being developed by ISRAD in view of Polarimetric application. It uses the Real time VxWorks Operating system for Multi Tasking with Power PC as the Core Hardware. It also uses the Xilinx FPGA for Digital Down Converter (DDC) for converting the 30MHz IF to Base band.

Tools: C, VC++ and MATLAB 7.0

Design, Developing and Coding

Confidential

Responsibilities:

• ISRO RADAR DEVELOPMEMT UNIT-ISRAD was responsible for the design, development and realization of state-of-art S-Band Doppler Weather Radar for use by India Meteorological Department for their Cyclone Detection Radar-CDR System. DWR characterizes severe weather events like cyclones, thunder storms and rainfall estimation. This Radar is installed presently at Space-Port SDSC-SHAR, Sriharikota and IMD is operating this radar round the clock.
• As a project Leader, played a key role in designing and developing the Real Time Data Acquisition and Processing (RTDAP) subsystem of DWR. This project is developed using PCI based TMS320C44 DSP Board. The Base band data is digitized and transferred to PC through PCI bus interface. The Data acquired in real time will be processed for estimating the Base Products like Reflectivity, Velocity and spectrum width of the Hydrometers. These Base products will be used mainly for nowcasting and forecasting of Weather.

Tools: MPLAB-C, Assembly language, Orcad

Designing, Developing and Coding

Confidential

Responsibilities:

• MCT Unit is mainly for monitoring the various status and Interlock parameters of the transmitter and controlling them accordingly in real time. This unit is designed with dsPIC30F6014 Microcontroller with additional Hardware for interfacing with various status and Interlock parameters. The system has the capability of processing 144-Digital I/O Lines, 16-Analog Input lines and 32 Command Lines. Acquisition and processing of the data is done for every 1 milli second. The Board is designed with TCP/IP, RS-232 and RS-485/422 interfaces for communication with the PC. The acquired data can be logged in the PC for troubleshooting and also for the off-line analysis. This unit has the unique capability of monitoring and controlling the Transmitter remotely. Software is developed in C using MPLAB tool as front end. MCT is designed in a generic way, so that the Unit can be interfaced to any subsystem in the radar for monitoring and controlling.
