Introduction

This project aims to deepen my knowledge and learning by researching how these features are implemented in software from major companies. To achieve this, I will attempt to recreate Amazon's system, exploring the best practices and techniques used in developing successful e-commerce platforms.

Note: This project is primarily intended for educational purposes, including my own learning journey. I am not affiliated with Amazon, Google, Facebook, or any other big tech company. I am undertaking this project solely to improve my knowledge. Therefore, implementations may not mirror those of industry giants like Amazon, but I will strive to do my best. This also allows beginners to study and learn from the project. Contributions and feedback are always welcome!
