Job Alert System

A full-stack microservice-based Job Alert System designed to deliver real-time job notifications to users based on their preferences.

---

🚀 Overview

The system is built with a microservices architecture, where each service handles a dedicated responsibility. Services communicate asynchronously through a Kafka event pipeline, ensuring scalability and reliability. Users instantly receive notifications when jobs matching their preferences become available.

🧩 Architecture

1. Job Search Service (Python)

   • Scrapes or fetches job listings from external sources.
   • Publishes job events to Kafka.

2. Job Alert Service (Nestjs)

   • Consumes job events from Kafka.
   • Matches job listings with user preferences.
   • Publishes matched events to Kafka for notifications.

3. Notification Service (Firebase)

   • Listens for matched job alerts.
   • Sends instant push notifications to subscribed users.

4. API Gateway (Nestjs)

   • Acts as a single entry point for client requests.
   • Routes requests to appropriate backend services.
   • Handles authentication and authorization.

5. Client Application (Next.js + TypeScript)

   • Provides a user-friendly interface for:
     • Job search
     • Subscription management
     • Real-time notifications

📡 Data Flow

1. Job listings are added through the Job Search Service.
2. Events are published to Kafka.
3. The Job Alert Service processes events and matches jobs with user preferences.
4. Matching alerts are forwarded to Kafka.
5. The Notification Service pushes alerts to users via Firebase.
6. The API Gateway and Next.js client allow user interaction and management.
