Waste Sorting App

The Waste Sorting App is a microservices-based application that helps users manage waste more effectively. It consists of 4 microservices (User, Category, Challenge, and Item) and a Gateway service to centralize API calls.

Architecture

The application follows a microservices architecture and uses the following components:

• User Service: Handles user authentication, registration, and profile management.
• Category Service: Manages waste categories such as recyclables, organic waste, and non-recyclables.
• Challenge Service: Provides challenges to users to encourage sustainable waste practices.
• Item Service: Tracks specific waste items, their properties, and disposal methods.
• Gateway: Acts as a centralized API gateway to route requests to the appropriate microservice.
