A practical roadmap for Data Engineers — build the platform that turns raw data into trusted, query-ready data. From SQL, databases, and data modeling to building pipelines with Spark, Airflow, and dbt, warehousing on the cloud, and the data quality, governance, and streaming that keep it all reliable.
Data engineering is a programming-heavy discipline built on top of solid coding and SQL. Get comfortable with a language and with querying databases before taking on pipelines and warehouses.
