Build across the boundaries

Make a whole thing.
Explain why it works.

Five substantial, synthetic projects bring the curriculum together. Each gives you staged requirements, failure cases, concrete tests, and an evidence notebook. Three now include editable multi-file starters, browser smoke experiments and separately downloadable reference solutions. Run full toolchains locally.

Build a production-style study board

Create an accessible team study-board application with typed requests, a real development database, scoped authentication, tests and a reviewable deployment artifact. Keep production services optional until the project needs a deliberate release.

Complete the debugging gauntlet

Build a disposable broken application from the supplied small fixtures, then diagnose independent input, async, database, layout and verification failures. Keep hypotheses, counterexamples and regression evidence for each repair.

Optional real toolchain bridges

These downloads execute locally or in the release verification environment, not in your browser. Each includes supported tooling, deliberate failures, a separate reference and exact commands.
