* Projected an idea to segregate the active bank accounts from inactive bank accounts which helped in increasing the
profit by providing offers to active account holders.
* Involved in feasibility study, design and development of the model to make sure that everything is done precisely and
efficiently.
* Concocted a model to predict credit decisions more accurately which helped to categorize loyal and active customers to
provide customized offers.
* Classified customers based on various factors to serve customers better using K-means algorithm.
* Used Generalized Linear Models (GLM) and Classification and Regression Trees (CART) to predict Customer Lifetime
Value (CLV) to predict customer with high future value.
* Used "User Based Collaborative Filtering" and ALS (Alternate Least Square) to recommend best products for loyal
customers, which helped in increasing customer retention.
* Involved in data refresh for creating a dashboard on monthly basis to reflect the correct visualization using Tableau.
* Worked with the big dataset for visualizing and creating models.
Project Details
Data Analysis Projects
* Project Name: Cross-selling Recommendation
Description: The Aim of this project was to use big data analytics technologies to conduct customer behaviour analysis
in terms of personalized cross-product buying and selling. Data set used for this project is from Amazon Product
Review and environment used is Spark and Python using Machine Learning methods.
* Project Name: Image Classification Using Neural Networks
Description: Image recognition is achieved by feeding an image into a neural network and obtaining some kind of label
for that image for the output. A label that matches the network output to a pre-defined class. There can be several
classes that can be labelled as an image, or only one.
* Project Name: London Housing Dataset
Description: Used the London Housing Dataset for predicting the price of house based on floor areas. To predict price
we used Python and Machine Learning Algorithms.
* Other Projects: Visualization Using R
* Dublin 2018 marathon dataset used to visualize factors affecting in winning marathon. Created a data model to
predict the winning trend.
* Speed dating dataset collected from dataworld compiled by Columbia Business School professors Ray Fisman and
Sheena Iyengar in 2002-2004. Applied random forest to find out which parameter effects the most in making a
decision for dating again the same person.
* Data Visualization using Tableau: Visualized the open source data set and created some of the meaningful
dashboards with it.
Achievements
* Worked as a student Ambassador in Maynooth University which includes responsibilities such as promoting the
university at various events, conduct guided campus tours and assisting recruiters visiting university for job fairs.
* Quite a few times became the performer of the month of the project while in TCS.
* I have been the hardest puncher of all my projects that I have worked on during my TCS career.
* Appeared and Passed several MCQs based competencies test on different technologies securing more than 80% on an
average in TCS.
* Volunteering in social and cultural events in school, college and university.
* Served as a School Captain.
