How you'll learn it
Four modes, in increasing order of difficulty. You read the trade-offs, watch me weigh them, make the calls yourself, then get scored on them.
Reading
Every decision and what it costs, plus a 7-step method you apply to every design.
Watching
Me designing on screen, thinking out loud through each trade-off.
Designing
Build the architecture yourself in the browser. Place the pieces, find what breaks at scale.
Testing
Timed mock interviews, plus chapter tests and a final exam.
Eight parts and 25 chapters, from distributed systems fundamentals to multi-tenancy and service mesh — including a .NET architecture chapter for the platform most of you ship on.
For backend engineers who want to reason about large systems with confidence — and for anyone preparing for a senior or tech-lead interview.
