A better way to learn backend systems

01

Learn the why first

Understand the pressure that creates a pattern before memorizing its implementation.

02

Practice the trade-offs

Apply every idea to systems you already know: feeds, payments, search, and messaging.

03

Build senior instincts

A deliberate 12-week sequence that turns scattered concepts into a connected mental map.

The curriculum

One connected map of modern systems.

No random lists. Each phase gives you the vocabulary for the next one, from database internals to AI infrastructure.

Made for deliberate practice

The sheet you’ll actually come back to.

Check off topics as you learn, copy the AI study prompt, work through real design exercises, and build a portfolio of systems you can explain.
