Hospital Management System
Enterprise Resource Planning for Healthcare
The Challenge
Hospitals need efficient systems to manage the complex relationships between patients, doctors, departments, and appointments. Manual scheduling leads to double-bookings, missed appointments, and poor patient experience. This system provides a centralized solution for healthcare administration.
System Architecture Flow
A layered architecture with Express.js server handling API routes, middleware for security, models for data access, and PostgreSQL for persistence.
Request Data Flow
Key Achievements
Optimized scheduling logic in PostgreSQL to prevent double-booking conflicts
Implemented Role-Based Access Control (RBAC) for doctors, patients, and admins
Built secure authentication with JWT tokens and password hashing
Created RESTful API with proper CRUD operations for all entities
Added rate limiting and security headers for production readiness
