Built a cross-platform Flutter application for real-time booking and tracking of home healthcare services. I designed and developed secure RESTful APIs with JWT-based authentication and multi-role access control (admin, staff, user). To ensure high availability, I deployed the Django backend on AWS EC2 with an Nginx reverse proxy, configured SSL/TLS via Let’s Encrypt, and managed DNS/domain routing. I also implemented structured API exception handling, retry logic, and GetX-based reactive state management on the Flutter client, ensuring a seamless user experience even under poor network conditions.
Developed a modular React.js frontend with role-based workflows for comprehensive issue tracking and resolution management. By building a reusable component architecture with centralized state management, I achieved a clean separation of concerns and accelerated feature delivery. Furthermore, I automated the entire build and deployment process using GitHub Actions CI/CD pipelines, serving the production build efficiently via Nginx static hosting on a Linux environment.
Architected and delivered a complete multi-role healthcare platform (caretaker, user, admin) end-to-end within just 3 months, acting as the sole architect and DevOps engineer. I built the backend using Django and DRF with role-based secure API design and a PostgreSQL database. To facilitate seamless remote consultations, I implemented WebSocket-based real-time communication for live chat, audio, and video call coordination. I also integrated the Razorpay payment gateway for secure advance and total payment processing, and deployed the entire infrastructure on AWS EC2 with Nginx, SSL/TLS, and Gunicorn.
