Low-Level Design for MAANG Interviews

A book-shaped table of contents for LLD interview prep: OOP fundamentals through SOLID, design principles, UML, design patterns, dependency management, reliability, concurrency, domain modeling, API design, testing, refactoring, classic interview problems, advanced architecture, and performance — cross-linking Object-Oriented Programming and Patterns instead of duplicating them.

Object-Oriented Programming for MAANG Interviews

A book-shaped table of contents for OOP: paradigm foundations, the four pillars, object relationships, SOLID/GRASP design principles, memory and runtime internals, GoF design patterns, language-specific OOP, and OOP at system scale — cross-linking existing pattern, concurrency, and low-level-design notes instead of duplicating them.

1 — SOLID Principles

Breaks down Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion — the five pillars of class-level design discipline.

3 — Object-Oriented Metrics

Breaks down Coupling, Cohesion, Complexity, Stability, and Maintainability as the core sub-topics of object-oriented metrics.

1 — Evolution of Programming Paradigms

Surveys Machine Programming, Procedural Programming, Structured Programming, Modular Programming, Object-Oriented Programming, Functional Programming, Event-Driven Programming, Reactive Programming, and Comparing Programming Paradigms as the core sub-topics of evolution of programming paradigms.
