ACADEMIC PROJECTS

Capstone project Jun – Aug 2019

Partnered with Diebold to build a predictive model that can predict if a particular work was billable or not.

Recoded and transformed variables to tensors to build the model.

Built deep learning neural network using R for Predictive analysis.

Evaluated models and generated/automated reports based on insights available from the data.

Student Retention Feb – Apr 2019

Worked with the Kent state University to develop effective data-driven strategy for student retention, student prospecting, graduation and retention rates, offer optimization etc.

Identified opportunities for increasing retention, marketing profitability, by exploring and analyzing of student behavioral data. In charge of statistical modeling operations for the project. Calculated the accuracy and took steps to improve the performance of the model.

Risky Lending Business Jan - Mar 2019

Worked on a project for Barclays bank for maximization of return-on-investment (ROI) on the issuance of small dollar loans. This optimization is supported through the accomplishment of two supporting goals: Determining the probability of default (PD)-logistic regression model, and loss given default (LGD)-linear regression model, of every applicant.

Credit card Fraud detection February 2019

Credit card fraud detection for a private credit card company using CRISP-DM. Performed PCA Transformation, feature selection. Built a tree-based model to predict fraud transactions and evaluated model using – AUC, Return on investment (ROI), Confusion matrix and statistics. Deployment.

Churn Prediction Aug - Dec 2018

Customer churn prediction on generic data from unknown US carrier. Performed feature selection and built Logistic regression model for predicting the churn probability. Used Tableau to create dashboards with plotted maps to present the insights. Model evaluation – AUC, Confusion matrix and statistics.

Developed SQL queries to generate weekly and monthly reports on customer claims and used data visualization to create real-time ROI graphs that helped to focus on high-profit business and deliver insights to the company on customer churn and acquisition.

Wells Fargo campus analytics Aug - Nov 2018

Built a machine learning algorithm that minimizes carbon footprint for each customer while maintaining their total quality of life by problem formulation, choosing the constraints, formulating the objective function. Performed optimization and created web application (shiny app) and presented the project with a live demo.
