Nubank Data Engineering with Sujith Nair

Nubank is a popular bank that is based in Brazil. Nubank has more than 20 million customers, and has accumulated a high volume of data over the six years since it was started.

Mobile computing and cloud computing have given rise to “challenger banks” that operate more like software companies. When a software company reaches the size that Nubank is at today, it needs a data platform.

A data platform is a collection of different technologies that move data into different storage formats and applications, so that different members of an organization can access that data. New data often enters an organization through an OLTP database, which supports user transactions. That data is copied into a data lake, which provides cheap bulk storage. From the data lake, the data is moved into a data warehouse system for fast access. Along the way, tools like Kafka, Spark, and S3 are used to implement the needs of the data platform.

Data platform architecture is not an exact science. Different companies build their data platform based on their own unique requirements. Previous shows have covered the data infrastructure companies like Lyft, Uber, and Facebook. Today’s show is another case study in data infrastructure, with a modern bank.

In a previous episode, we covered the engineering of Nubank. Sujith Nair from Nubank joins today’s show to talk about the data infrastructure of the company.
