Quick Health - A Doctor Appointment Booking System
Abstract
The Quick Health project is a web-based doctor appointment booking system developed
using the MERN stack (MongoDB, Express.js, React, Node.js). This system aims to
streamline the process of scheduling medical appointments by providing a user-friendly
platform for patients, doctors, and administrators. Patients can search for doctors, book
appointments, and manage their schedules, while doctors can manage their availability
and view patient details. Administrators oversee the system, managing user accounts and
ensuring smooth operations. The system incorporates secure user authentication, realtime notifications, and a responsive interface to enhance accessibility. By automating the
appointment booking process, Quick Health reduces manual effort, minimizes scheduling
conflicts, and improves healthcare accessibility. The project leverages the scalability and
flexibility of the MERN stack to deliver a robust and efficient solution. Future enhancements include integrating telemedicine features and AI-based health recommendations.
