Confidential, Midvale UT

Data Scientist

Responsibilities:

• Used Random Forest Classification in sklearn to build look alike models - Data exploration, Outlier Analysis, Imputing missing values, Correlation Tests, Multicollinearity checks, Model building and hyper-parameter tuning. dentifies customers having similar profiles to any of the current ClubO customers.
• Identifies customers having similar profiles to any of the current Confidential cardholders.
• Grouped similar profiled ClubO customers using clustering to create segments and used classification method to identify non-ClubO customers having similar profiles to the ClubO segments. Used PCA, K-means clustering and Random Forest Classification.
• Built a regression model to predict an optimal date to send reminder email to buy again same product from Health and Beauty store.
• Used Lasso Regression in spark Databricks.
• Used Logistic Regression technique and wrote SAS codes throughout - Data exploration, creating derived variables, Outlier Analysis, Data Transformations, Collinearity tests, Variable reduction, Model building and evaluation
• Predicted probabilities for customers’ response to a social media campaign. Customers who have been targeted through social campaigns in the past were taken with both audience and responders.
• Predicted probabilities that a customer would buy from a store where they have not already purchased. Logistic regression model is built for each store to predict probabilities at customer level.
• Used ARIMA method in SAS to predict weekly Nectar forecast.
• Supported ClubO by tracking various ClubO program performances and suggested on improvements.
• Conducted AB testing and profiled customers with all channel related metrics.
• Monitored channel growth in terms of ClubO signups and profit.
