What it is
What Data Engineering does
The same 400-lesson format applied to data engineering: ingestion, modelling, orchestration and warehousing, with runnable labs and a curriculum-grounded offline tutor.
Forty courses covering ingestion, transformation, modelling, orchestration and warehousing, with the same runnable-lab structure: you build the pipeline and watch it fail before you read why it failed.
Everything runs on-device, including the tutor, so a work laptop with no cloud access is still a full learning environment.
How it does its job
Architecture decisions
Choose a design, then see the consequence.
Offline tutor
Grounded in the curriculum, available without a network.
What it doesn't do
Vendor-specific consoles change constantly; this teaches the transferable shape, not this quarter's UI.
