Every scalable API needs a bouncer. Rate limiters seem straightforward at first, but get deep fast once you factor in distributed counters, race conditions and strict latency budgets. Walk through the iterations with Archie reviewing each step. archie.guru/case-studies/rat…

The URL shortener is the gateway drug to system design. Simple enough to start, deep enough to teach caching, replication, edge delivery, and abuse handling. Walk through five iterations with Archie reviewing each step. archie.guru/case-studies/url…

Most “architecture evolution” graphics are helpful and misleading at the same time. Helpful because they give a mental model. Misleading because they imply every app evolves in the same neat path. This graphic is a map, not a rulebook.

That’s a much better mindset than memorizing boxes. If you’re learning system design, focus less on “what components exist” and more on: • what triggers change • what trade-off you’re making • what fails next • what simpler option you might be skipping
