A strong case study starts with a real problem. Describe who needed the system, what constraints mattered, and what success would look like.

Discuss the tradeoffs

Why did you choose this storage model, API shape, or deployment pattern? Mention the alternatives you considered and the costs of your choice.

Show evidence

Add tests, performance measurements, reliability improvements, or a working demo. If you cannot measure an outcome, explain what you learned without inventing a number.
