Who is a Data Engineer?
A data engineer is a professional who is responsible for the design, construction, and maintenance of the infrastructure and systems that are used to store, process, and analyze large and complex sets of data.
They work closely with data scientists and analysts to create and implement data systems that can handle vast amounts of data, and that is optimized for performance and scalability.
They also ensure that data is accurate, complete, and easily accessible to other members of the organization who need it.
Data engineers are responsible for maintaining the data pipeline, data storage, and data processing systems that enable organizations to turn data into actionable insights.
The role is becoming increasingly important as more organizations are looking to leverage big data and machine learning to gain insights and make better decisions.

Data Engineer; What do they do?
Data Engineers work to ensure that data is accurate, complete, and readily accessible to others who need it.
Their main tasks include:
- Designing and building data pipelines: Data engineers create and implement data pipelines that can handle large and complex data sets. They use tools such as Hadoop, Spark, and Kafka to build and maintain data pipelines.
- Storing and processing data: Data engineers work to ensure that data is stored in a way that makes it easy to process and analyze. They may use data warehousing solutions such as Amazon Redshift or Google BigQuery to store and process data.
- Ensuring data quality: Data engineers ensure that data is accurate, complete, and consistent. They may use data quality tools to validate and clean data before it is loaded into a data warehouse.
- Securing data: Data engineers are responsible for ensuring that data is protected against unauthorized access. They may use encryption and other security measures to protect data.
- Optimizing performance: Data engineers work to optimize the performance of data systems by monitoring and troubleshooting issues. They may use performance monitoring tools such as Amazon CloudWatch or Google Stackdriver to track the performance of data systems.
- Collaborating with data scientists and analysts: Data engineers work closely with data scientists and analysts to understand their data needs and design systems that meet those needs.
- Continuously improving: Data engineers continuously improve the data pipeline and infrastructure by implementing new technologies and best practices.
