[13] Proxy Design Pattern | Mastering Low-Level Design

In this thirteenth episode of the Mastering Low-Level Design series, we dive into the Proxy Design Pattern — a structural design pattern that provides a surrogate or placeholder for another object to control access to it. Proxy is incredibly powerful when you need to add functionalities like lazy loading, caching, access control, logging, or remote access — all without changing the actual object.

🔍 What’s covered in this video:
What is the Proxy Design Pattern
Real-world analogy and use cases (e.g., credit card, API gateway, Hibernate lazy loading)
Types of proxies: Virtual, Protection, Remote, Caching, Smart
Java implementation using a caching proxy for slow API
Benefits: access control, performance optimization, logging, and testing
When to use Proxy in real-world systems
Best practices to implement Proxy with Dependency Injection

This video is perfect for Java developers, interview candidates, and backend engineers who want to understand how to apply structural patterns to build clean, maintainable, and flexible systems.
