Data engineers are essential in facilitating businesses to make informed data-driven decisions, operational efficiency, and provide important insights. As organisations increasingly rely on big data to guide their strategies, data engineers play a critical role in designing, building, and maintaining the infrastructure required for collecting, storing, processing, and analysing large datasets. Data engineers significantly contribute to the success of initiatives based on data and the overall digital transformation of an organisation by offering knowledge in data design and management, which in turn drives development and innovation.
