Free, structured learning paths
built by an engineer who ships.
No fluff courses. No upsells. The best material for every one of these topics is already free on the internet — the missing piece is structure. Each path tells you what to watch, in what order, what to build after each level, and what to skip.
Mastery Library →
The best books, docs, courses, channels & GitHub repos for 24 engineering domains. Searchable. Free.
Career OS →
The $15/hr→$1M roadmap, freelance & SaaS blueprints, and the daily systems of top engineers.
My Learning →
Track progress across every course, keep a build log, and save resources. Sign-in optional.
Pick a path
Each course is a complete roadmap to one real outcome — not a topic dump.
Follow levels in order
Every level is sequenced: watch, read, then build. Skip rules tell you when to jump ahead.
Build the projects
That's where the learning happens. Each build ships with acceptance criteria — you'll know when it's done.
Most paid courses repackage free content.
The best material for every one of these topics is already free — freeCodeCamp, MDN, official docs, Karpathy, Anthropic's own guides. The problem was never access; it's structure. This academy solves structure: what to watch, in what order, what to build after each level, and what to skip. I use these exact resources myself — the AI engineering path is the one behind the 24-agent system that develops this site's own codebase.
