  Combining internal proprietary customer data along with publicly available sources (Census, Economic Census, open government data, etc.), I built models for predicting consumer behaviour in rural Indian markets. • Model for early identification of defaulters in small business loans: predicted profits from using the model showed 100% improvement over existing approaches. Reduced costs by using only public datasets. • Model for predicting loan renewals in Self-Help Group microfinance… Show more Combining internal proprietary customer data along with publicly available sources (Census, Economic Census, open government data, etc.), I built models for predicting consumer behaviour in rural Indian markets. • Model for early identification of defaulters in small business loans: predicted profits from using the model showed 100% improvement over existing approaches.
