· Feature Store: Wrote a utility Feature Store which comprises of a framework to define aggregation features across different data sources and a user facing API. API is written to be flexible with distinct time-frame for individual users and can aggregate features at mutliple levels: city, cluster of cities, country.

We identified a sizable chunk of the population with less than 0.5 percent chance of defaulting. A balanced bagging classifier was built on top of curated set of features for this skewed classification problem.
