    A full-featured job portal application that allows recruiters to post and manage job listings, and job seekers to find, apply, and track job applications — with a seamless real-time chat system connecting them.

    This project showcases real-world, production-ready features such as:

    🔐 Authentication and role-based access

    📄 Resume uploads with automatic S3/local detection

    📬 Email notifications via RabbitMQ-based microservice

    🧠 AI-powered resume-to-job matching using Hugging Face

    🗂️ Application status tracking with history and comments

    🔎 Filtering, pagination, and admin-level CRUD operations

    💬 Live chat with offline message sync and unread badges

    🌐 Multilingual support with 10 languages via i18next

    The backend leverages a modular microservices architecture for improved scalability:

    Email notifications are offloaded to a dedicated RabbitMQ-powered email microservice.

    Resume-job matching is powered by a standalone LLM-based microservice, deployed securely and independently.

    These design choices decouple long-running or compute-heavy tasks from the main app, improving responsiveness and enabling future scalability.
