· Built an application scorecard (probability of default model) using existing bank customer data using Logistic Regression (Binary Classification) as baseline mode with an accuracy of 65% and GINI co-efficient of 40%. Have compared baseline model with other sate of art algorithms like Random Forest and XGBOOST. Wrote an efficient code in python for feature engineering like creating weight of evidence and information value and selected significance predictors for model through this process.

· Performed Cramer's V (CHI-SQUARE) for good ness of fit test for available set of categorical variables.

· Built K-means clustering in Python to segment a dataset of customers into groups based on customer behavior metrics of Credit Card. Objective is to find 3 clusters of income group(Elite, Premium, Basic). It is an adhoc project for one of credit card campaign.
