Every backend developer hits this moment:

Your API is working fine…

Until suddenly it’s not.

* Too many requests
* Slower responses
* Repeated database/API calls
* Same data being fetched again and again

And you realize:

* Distributed caching
* Complex setups
* Extra infrastructure

For many projects, especially small to medium apps, this feels like:
