  • Role: Web Developer.
  • Team Size: 8.

Proligence Technologies Hyderabad :      Jan 2014 - June 2015

Member get Member is a short URL capability provided to the American Express. A MGMer can have multiple product id mappings and the respective short URL's can be generated by using MGM. On logging in into POA hub system which allows us to log in using myca or account, will generate shorty URL.
Short URL is a secured web service developed and implemented by shorty. It accepts different parameters from the POA hub and communicates with the myca system to get the complete details. Based on the information retrieved from the myca, the shorty will be generated and sent back to the POA Hub interface.

  • Project: Designing Pulse Width Modulation Circuit Board.
  • Technologies:OrCAD Capture.
  • Role: Hardware Design Engineer.
  • Team Size: 4.

The critical component that defines the quality of the output wave is Pulse width modulation, it also defines the efficiency and quality of the Uninterrupted power supply system, as a team, we have redesigned the Pulse Width Modulation module, and redesigned the space vector modulation algorithm for effective sampling.

Roles & Responsibilities

  • Designed PWM circuit Board.
  • Designed Switched- mode power supply board.
  • Conducted testing of existing products and initiated ways to improve the existing circuit.
  • Evaluated design and test data and prepared technical specifications report

Serco Inc:      Dec 2011- May 2012

  • Project: Google Maps validation.
  • Client: Google.
  • Technologies:Google maps Engine.
  • Role: Validation Analyst.
  • Technology Used: Google maps Engine lite.

Google maps the market is the leader in providing web mapping service which offers satellite imagery, as a team, we were into developing maps using Google maps engine lite, wherein the data that is collected using multiple sources from satellite, and aerial information was processed.

Roles and Responsibilities

  • Created, maintained, and updated Geographical Information System (GIS) data.

Course Work

Project 1:  

Technology Used: Python, Numpy, Scipy, Panda, Matplotlib.

As an Individual Project, I was asked to take any data set and implement Machine learning algorithm, Classification, Regression, and assess using K-fold Cross- validation, I have chosen the famous Fisher's Iris data set which consisted of 50 samples of three varieties of flowers species and four parameters were measured from each of those sample length and width of the sepal and petal in centimeters, and implemented all the requirements.

Project 2:  
Development of Smart Card Based Energy Meter and Theft Analysis Technique.

Technology Used: OrCAD, PSpice, and Micro Controller Programming

As a group project, we were asked to find out innovative methods to help detect un - authorized usage of electricity. We designed smart card based energy meter, the project highlighted how unauthorized electricity tapping could be prevented, we demonstrated working model by assigning a unique code to every transformer on the distribution side, circuit and algorithm was designed to monitor real-time power flow and consumption, GPS was used for location whenever there arises power variation the microcontroller sends the unique code of the transformer located in that area to the control room displaying the address and location of the transformer.

Roles and Responsibilities

  • Lead a team of a designing model, developed required hardware circuit using OrCAD Capture.
  • Tested voltage and current parameters using P-Spice.
Coding,Reading, Running, Travelling.
