• Exposes the costly mistakes juniors make without realizing it
• Gives you a line to remember under pressure for every decision
• Spans the full stack: ingestion, storage, modelling, Spark, streaming, distributed systems, the lakehouse and platform

• Clean, screenshot-friendly, and straight to the point — zero filler
