System Design
Designing systems that scale without falling over.
System design is where the individual pieces — services, databases, caches, queues — have to work as one system. This hub covers scaling strategies, distributed-systems trade-offs, consistency and concurrency, and the architecture decisions that decide whether a system stays up as traffic grows.
It is the connective tissue between the Node.js, PostgreSQL, and Redis hubs, and it draws on the patterns from those series.

Frequently asked questions
Are these system design articles interview prep or real engineering?
Both, but the emphasis is real engineering — how scaling, caching, queues, and consistency actually behave in production. That grounding is exactly what makes the interview version credible.
