The Computer Science Roadmap

Most self-taught developers pick up computer science in a random order — a bit from a video here, a blog post there — and end up with gaps they can’t even see.

This free, 45-page roadmap lays out the whole territory: the core areas of computer science, the order that actually makes them click, and the parts you can safely skip when you’re learning on your own.

What’s inside

• What to learn — the major areas of computer science and how they fit together.
• In what order — a carefully planned sequence from fundamentals up to systems, tailored to your situation.
• What to skip — the topics that aren’t worth your time right now.

Who it’s for

The roadmap charts a separate path for four kinds of learner:

• Working developers — you can ship, but you can feel the sand under your feet. You want to know what you’ve been missing, and how far to trust your AI tools.
• Just starting out or switching careers — you can code a little, but how it all fits together is still a mystery. You want a way in that doesn’t assume you already know the jargon.
• Interview preppers — you need real mental models of algorithms, data structures, and system design, not rote answers that fall apart under questioning.
• Future CS students — you’re weighing up whether to study computer science, and you want an honest overview before committing years to it.
