Course roadmap
Modules are in the recommended order, and every lesson is open from day one.
Application Design and Contracts
Turn scripts into understandable applications by making domain rules, interfaces, and dependencies explicit.
Asynchronous Workflows
Coordinate independent I/O while keeping deadlines, cancellation, and bounded work visible.
Testing and Release Boundaries
Build confidence at contracts and seams, then package a small application with a reproducible entry point.
