> 🔨 A production-style Product API backend built with Spring Boot, integrated with **FakeStore API** and enhanced by **custom exception handling**, global error responses, and clean architecture.

---

## 📘 Overview

This project showcases a fully functional Product Management API built with `Spring Boot`. It integrates with the public [FakeStore API](https://fakestoreapi.com/) to perform real-world operations like create, read, and update products.

It focuses on writing **scalable**, **clean**, and **debug-friendly code** using best backend practices.

## 🚀 Features

✅ Create Product  

✅ Get All Products  

✅ Update Product by ID (PATCH)  

✅ Custom Exception Classes for clarity  

✅ Global Exception Handling with `@ControllerAdvice`  

✅ External API Integration using `RestTemplate`  

✅ Clean and modular service-layer architecture  

✅ Debug-friendly logs and response messages
