Experience

  • Senior Hardware Development Engineer

    Western Digital

    April 2016 – Present(3 years 6 months)Orange County, California Area

    • Worked as a Firmware engineer in the enterprise SSD HW Product Validation group. • Resolved the power gap issue of up to 1.5W between actual drive reported power and the FW reported power by optimizing the power throttling algorithm in the product FW. • Worked closely with the platform firmware team in resolving FW jiras related to SMBUS interface and nvmc tool support. • Created FW test code builds by making changes to the Flash and DDR parameter settings for validation. • Developed a control loop algorithm to monitor ASIC DUT temperature and to control the fan speed. • Developed automation tools for four corner TVS testing, Temperature Power Performance Testing, Input delayed Power Sequencing Testing and Noise injection testing as part of SSD HW Validation. • Performed electrical validation on multiple enterprise SSD PCIe products including Clock Integrity testing, Voltage Regulator Sequencing Testing, Hot Plug Testing and I2C interface testing. • Developed python modules to enable SCPI based communication with test equipments like Power Analyzer, Oscilloscope, Temperature Chamber and Quarch PPM.

  • Embedded Software Engineer

    Nemo IT Solutions, Inc

    August 2015 – March 2016(7 months)

    Developed a Step counting algorithm using the accelerometer and gyroscope readings for fitness related products.Optimization is done to count the number of walking steps, the number of running steps, and the number of hopping steps using C and MATLAB.

  • Firmware Intern

    Roambotics, Inc.

    June 2014 – June 2015(1 year)Tempe, Arizona

    • Worked on the stabilization of a unicycle autonomous robot (Roambot) by integrating all the sensor inputs using Kalman Filter and programmed it using ARM STM32F405 development board using Embedded C & MATLAB. • Designed the Printed Circuit Boards (PCB) which includes the ARM STM32F405 controller and different analog sensors for the robot using Eagle Software. • Simulated the motion of the robot using Blender 3D software using python.

  • Polypower energy scavenger

    IEEE

    March 2013

    Vibrational energy is available from structures such as bridges and in many industrial and automotive scenarios and this had led to the development of novel Energy scavenging technique, that is introduced to harness ambient energy from the vibrations. Design of vibration energy harvester is done through Polypower films that act as intelligent elastics, as it is capable of generating electricity from mechanical vibrations. The proposed system behaves like a perpetual device that produces effective regulated output when implemented in an array fashion. The vibrational energy from test system is tapped using Polypower film which is rolled around the system in form of sheets that damp the vibrations as well as harvest energy by damping. The signal conditioning and amplifying unit produce regulated output.

    IEEE

    February 2013

    Mems based implantable drug delivery and minimally invasive systems are currently used for regular monitoring of cardiac energy balance. Here we have proposed a novel system for measuring intracardiac bio-impedance and application of Mems piezoelectric diaphragms actuates the micro pump and injects the drug using micro needle. Pressure gradients across heart valves are measured using this system thereby extending the system to a Biomimetic of Heart- On- Chip
