From chapter 1, 1 h 13 min
Take one small app, Errand, apart and rebuild it one concept at a time: where data changes shape between layers, how to debug from evidence instead of guessing, fake APIs and test doubles, synchronous and asynchronous work, signing in and OAuth with PKCE, background workers that stop safely and resume, domain boundaries and contracts between teams, and search that forgives typos. Every chapter starts from a real problem and ends with something you build and test. Module 1 is available now; the other modules follow.
Read the course: the same chapters with diagrams, labs and quizzes.
