# Retailer System

## Overview

The Retailer System is a robust online marketplace where retailers can showcase their products, and users can browse and make purchases securely from the comfort of their devices. The application is designed with a stringent regulatory process, ensuring that both retailers and products are thoroughly reviewed and verified by administrators before becoming accessible to users.

## Key Features

- **Secure Authentication:** Implemented JWT token-based authentication for secure user validation, providing authorized API access.

- **Google Cloud Integration:** Utilized Google Cloud Platform (GCP) services, including Buckets and BigQuery, for dynamic data storage, flexible querying, and real-time updates.

- **Microservices Efficiency:** Integrated Axios for streamlined microservices operations, ensuring efficient communication between components.

- **Real-time Data Processing:** Leveraged KafkaJs as a Pub/Sub system for handling real-time streaming data, distinguishing Producers and Consumers.

- **Order Fulfillment Process:** Enabled users to select items, create orders, and process payments, ensuring a seamless order flow.

- **User and Retailer Registration Workflow:** Designed secure sign-up processes for users and retailers, pending admin approval. Admins reviewed and either accepted or rejected applications.

- **Retailer Item Submission Workflow:** Allowed retailers to submit products for approval, storing them in a relay table for admin review. Admins approved or dismissed items based on their criteria.

- **Metrics and Monitoring Integration:** Integrated Prometheus for real-time metric recording, providing essential data for application analysis. Dockerized the application and connected it with Prometheus and Grafana for enhanced monitoring.
