Design and Development of a Job Portal Using MERN Stack for Efficient Recruitment Management

Abstract

The Job Portal System is a web-based recruitment platform developed using the MERN stack—MongoDB, Express.js, React.js, and Node.js—designed to modernise and streamline the hiring process for job seekers, recruiters, and administrators. Traditional recruitment methods suffer from fragmentation, manual effort, and limited accessibility; the proposed system addresses these limitations by providing a centralised, automated, and user-friendly environment for allstakeholders. The architecture is organised into three primary modules: the Applicant Module, enabling profile creation, resume upload via Cloudinary, job search, and online application; the Recruiter Module, supporting company profile management, job posting, applicant review, and status updates; and the Admin Module, providing systemwide oversight of users, jobs, and data integrity. Security is enforced through JSON Web Token (JWT) based stateless authentication and BCrypt password hashing. The frontend delivers a responsive, component-based interface built with React.js and Tailwind CSS, while the backend exposes RESTful APIs via Node.js and Express.js. MongoDB serves as the NoSQL data store for user, job, company, and application records. The system demonstrates the practical application of full-stack web development principles in solving real-world recruitment challenges, offering a scalable foundation for future enhancements including AI-based resume screening, personalised job recommendations, and real-time notification systems.
