Denze: Healthcare Clinic Platform Developer Case Study

Project Overview

Denze is custom healthcare software and a multi-portal platform designed specifically for dental clinics. As the lead healthcare clinic platform developer on this project, I architected a unified ecosystem comprising distinct portals for Clinic Admins, Doctors, Receptionists, and a Public Website. By separating concerns between a React.js frontend and a Django backend, I ensured that the application remains fast, secure, and highly scalable.

The platform simplifies the day-to-day operations of dental clinics, allowing staff to manage inventory, book patient appointments seamlessly, and maintain comprehensive electronic medical records (EMR).

Technical Architecture & Backend

To support high availability and secure data transmission, the backend is built entirely with Django and the Django REST Framework (DRF), exposing a robust REST API for the frontend clients. The database layer utilizes PostgreSQL, taking advantage of transactions and row-level locking to handle concurrent appointment bookings without double-booking errors.

Role-Based Access Control (RBAC) was a critical requirement. I implemented JWT-based authentication to manage stateless sessions securely across all micro-frontends, ensuring that a receptionist cannot access sensitive clinical configuration data meant only for the clinic administrator.

Key Features Developed

• ▹

  Scalable Frontend: Designed an architecture organizing 20+ business domains including Inventory, Appointments, and Patient Management.

• ▹

  Interactive Clinical Charting: Developed an interactive SVG-based dental charting system enabling doctors to perform visual tooth selection and record diagnoses directly onto the patient's virtual chart.

• ▹

  Secure API & RBAC: Implemented comprehensive role-based access control using JWT authentication, protected routing in React, and centralized Axios interceptors for automatic token refresh.

• ▹

  Reliable Database Transactions: Architected a multi-branch inventory management system utilizing PostgreSQL transactions to prevent race conditions during high-volume stock updates.

• ▹

  Cloud Deployment: Automated the deployment pipeline, ensuring that the frontend static assets and backend API containers are highly available to medical staff 24/7.
