🏗️Data Engineering Foundations
An eight-lesson path from SQL fundamentals to a modern data stack. You'll learn how to query and tune relational data, cache hot reads, model with dbt, choose between lakehouse and warehouse architectures, and wire pipelines together with Kafka and Airflow. By the end you can reason about every layer a production data platform actually runs on.
