Amidst rapidly changing conditions, many companies build ETL pipelines using ad-hoc strategy.

However, this approach makes automated testing for data reliability almost impossible and leads to ineffective and time-consuming manual ETL monitoring.

Software engineering decouples code dependency, enables automated testing, and powers engineers to design, deploy, and serve reliable data in a module manner.

As a consequence, the organization is able to easily reuse and maintain its ETL code base and, therefore, scale.

In this presentation, we discuss the challenges data engineers face when it comes to data reliability. Furthermore, we demonstrate how software engineering best practices help to build code modularity and automated testings for modern data engineering pipelines.
