System Design, taught as mental models

#1 System Design Sheet

Build mental models, not checklists

Understand why a system exists, not just its API. A 12-week backend engineering roadmap that connects the dots.

Study with AI by your side

Every week is structured for ChatGPT, Claude, or your preferred assistant. Includes a ready-to-use study prompt.

Built for backend engineers

Interview prep, distributed systems, or leveling up. 5–6 hours a week, two focused sessions, topics that build on each other.
