Lessons are being authored
This module is visible so you can understand the full roadmap. Its lesson pages will open after their beginner-friendly explanations and review material are ready.
Write clean, extensible, thread-safe object-oriented code, eliminate design code smells, apply GoF design patterns appropriately, and model domains with DDD entities and value objects.
Proficiency in an object-oriented language (Java, C++, TypeScript, Python, or Go).
Good low-level design minimizes the blast radius of future changes. We design to abstractions, protect invariants with encapsulation, and compose small, cohesive components.
