Design Patterns Used

Strategy Pattern for Initializing Upload and Creating a Presign URL

I utilized the Strategy Pattern to handle both Single File Upload and Multipart Upload dynamically.

Singleton Pattern

The Singleton Pattern is used in this project to ensure a single instance of critical resources such as - Database Connection, AWS Session, RabbitMQ Connection
