Why This Course Series?

There's plenty of free content on system design. Here's why this is different.

A Framework That Doesn't Exist Elsewhere

YouTube videos teach you about Stripe APIs. Blog posts explain payment flows. But where's the systematic framework that ties it all together?

7 building blocks. Every system. Same patterns. This framework was developed over 10 years of teaching at UC Berkeley.

Feedback On Your Thinking

Free resources teach you concepts. They don't tell you if you're applying them correctly.

This course series includes AI-powered feedback on your assessments and design challenges. Submit your designs. Get specific feedback on what you got right and what you missed.

A Rare Combination

20+ years building commercial software at scale.
10+ years teaching at the university level.

Most practitioners can't teach. Most teachers haven't built. This course is designed by someone who's done both.
