ABSTRACT
The rapid digitalization of healthcare services in India has exposed critical gaps in service integration, emergency responsiveness, and equitable access, especially in semi-urban and rural regions. This paper presents Seva, a full-stack, real-time digital healthcare platform developed using the MERN (MongoDB, Express.js, React.js, Node.js) stack. Seva unifies multiple essential healthcare services—hospital appointment booking, online medicine ordering, real-time ambulance tracking within a 15-kilometer radius, and secure diagnostic report management—into a single, user-centric system. A unique feature of the platform is its ability to allow patients to upload their own medical reports and optionally forward them to hospitals they have booked, fostering continuity of care and improving clinical coordination.
Seva is built with a modular, role-based architecture that supports patients, doctors, hospital administrators, ambulance drivers, and pharmacists through secure interfaces. The platform employs JWT-based authentication, file upload protection using Multer, SMS/email notifications via Twilio and Nodemailer, and location visualization through React Leaflet and OpenStreetMap. The system was evaluated under simulated real-world conditions, achieving strong performance in low-latency operation, role-specific data control, and service reliability.
The paper also explores Seva’s potential to support government health programs, NGOs, and remote care delivery, while promoting environmental sustainability through paperless prescriptions and reports. The platform’s open-source and customizable design positions it as a scalable and socially impactful solution for bridging India’s healthcare access gap. Seva demonstrates that full-stack digital innovation—when ethically designed and contextually aware—can offer not only technical efficiency but also lasting societal value.
