DaryeelOne

Overview

• DaryeelOne is a modular hospital management system built to streamline clinical workflows, patient registrations, doctor scheduling, electronic medical records (EMR), pharmacy inventories, and billing operations under a unified full-stack architecture.

Architectural Data Flow

The Problem

• Healthcare facilities require a reliable, structured platform to manage patient care, clinical scheduling, and billing records with strict authentication and role boundaries.

The Solution

• Developed a responsive React + TypeScript interface consuming typed REST APIs backed by a PostgreSQL database, packaged into Docker containers for reliable cluster deployment.

Architecture

• React + TypeScript frontend providing modular admin and clinical interfaces.
• Express.js backend exposing RESTful APIs with JWT authentication middleware.
• Prisma ORM managing transactional database migrations and typed queries against PostgreSQL.
• Docker packaging the frontend and backend services into portable container images.
• Kubernetes orchestrating pod deployments, internal service networking, and persistent storage.

Technology Stack & Tools

Healthcare & System Modules

• Patients Registration & History
• Doctors & Staff Directory
• Departments & Ward Management
• Appointments & Scheduling
• Electronic Medical Records (EMR)
• Pharmacy & Medication Inventory
• Billing & Invoicing Workflows

Infrastructure & Containerization

• Docker multi-stage files building production-optimized static assets and backend runtimes.
• Kubernetes manifests defining Deployments, ClusterIP Services, ConfigMaps, and Secrets.

CI/CD & Deployment Pipeline

• Automated CI testing and image containerization triggered via GitHub Actions.

Engineering Highlights

• Modular healthcare administration architecture
• React + TypeScript single-page application frontend
• RESTful Express.js backend API with Prisma ORM
• Relational PostgreSQL database for medical records
• Docker containerization for local and cluster environments
• Kubernetes workload manifests and service definitions
• GitHub Actions CI workflow for build validation

Architectural Decisions

• Selected TypeScript across frontend and backend for end-to-end type safety.
• Used Prisma ORM to guarantee structured database migrations for medical schemas.
