System Design Laws
The laws that govern every system at scale.
This newsletter breaks down the principles behind how systems at Netflix, Uber, Stripe, and Amazon actually run - not diagrams for show, but the mental models that separate junior engineers from senior architects.
What you’ll learn
Patterns that scale: caching, queuing, consensus, sharding and when each one is the right trade-off
How systems fail: single points of failure, eventual consistency, and where real outages come from
What you can use on Monday: one law at a time, with enough depth for design reviews and interviews
