🎓 System Design Mastery Program

Target Audience: Senior & Staff Engineers

---

This program is structured in 4 phases, 20 modules. Each module follows the same narrative format as the Factory Method example — an engineering story with a villain, hero, plot, and twist. Modules progress from foundational systems to GenAI-specific architecture.
