Design systems that scale, reason about the tradeoffs, and brief the design so anyone can follow it.
System design is where engineering careers open up or stall. It is the skill senior interviews test hardest, the conversation that decides which projects you are trusted with, and the thing that separates someone who can write a service from someone who can architect one. It also has a reputation for being mysterious, a matter of memorizing diagrams and buzzwords. It is not. It is a small set of building blocks, a handful of hard tradeoffs, and a way of reasoning about them out loud.
This course teaches both halves: how to design systems that scale and stay reliable, and how to brief a design so that an interviewer, a team, or a skeptical architect can follow your reasoning. You will learn to turn vague requirements into concrete numbers, assemble the standard components, scale reads and writes, choose data stores, reason about consistency and the CAP theorem, and build for failure. Throughout, you will practice the structured way of presenting a design that makes interviewers and colleagues trust you. The teaching is grounded in the field's core texts, above all Martin Kleppmann's work. Every chapter ends with a quiz, and the course ends with a timed final exam and a verifiable certificate.
Ravi Menon has designed and operated systems at scale for over a decade and has interviewed hundreds of engineers on system design. He is convinced that most people who fear the subject simply were never shown that it is a reasoning skill, not a memorization contest, and he teaches it that way.
