A comprehensive guide to layered (N-tier) architecture: presentation, business logic, and data access layers, strict vs relaxed layering, dependency direction, common mistakes, and when layered architecture breaks down.
Master the Prototype design pattern with TypeScript, Python, and Java examples. Learn shallow vs deep copy, prototype registries, and when cloning objects is better than creating new ones from scratch.
A deep dive into monolithic architecture: what it is, when it's the right choice, how to structure a well-organized monolith, scaling strategies, common anti-patterns, and when to consider breaking it apart.
Master the Builder design pattern with practical TypeScript, Python, and Java implementations. Learn how to construct complex objects step by step, implement fluent interfaces, and avoid the telescoping constructor anti-pattern.
Master software architecture patterns from monoliths to microservices. A comprehensive roadmap covering layered, event-driven, hexagonal, clean architecture, CQRS, DDD, serverless, and how to choose the right pattern.
Master the Factory Method and Abstract Factory design patterns with practical TypeScript, Python, and Java implementations. Learn when to use each pattern, how they differ, and real-world use cases in UI toolkits, cross-platform apps, and plugin systems.
Master the Singleton design pattern with practical implementations in TypeScript, Python, and Java. Learn eager vs lazy initialization, thread safety, the anti-pattern debate, testing challenges, and modern alternatives like dependency injection.
Master the five SOLID principles of object-oriented design. Learn Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion with practical before/after examples in TypeScript, Python, and Java.
Master polymorphism and interfaces in object-oriented programming. Learn compile-time vs runtime polymorphism, method overloading and overriding, interface-based design, duck typing, and the Liskov Substitution Principle with practical examples in TypeScript, Python, and Java.
Master inheritance and composition in object-oriented programming. Learn when to use 'is-a' vs 'has-a' relationships, method overriding, the super keyword, mixins, and why you should favor composition over inheritance with practical examples in TypeScript, Python, and Java.
