React Healthcare PWA Build

I’m ready to move from concept to code on a healthcare-focused Progressive Web Application and I want it developed with modern React best practices from the ground up. The product should feel just like a native app—offline-capable, installable, and quick to launch—yet remain entirely web-based for cross-platform reach.

Core functionality I need implemented:
• Appointment booking with calendar integration and real-time slot availability
• Secure patient data management (role-based access, encrypted storage, export/import)
• Telemedicine/consultation via browser-based video and chat, including basic waiting-room logic

Acceptance criteria for hand-off:
• A responsive React PWA that passes Lighthouse PWA audits (scores ≥ 90 for Performance, Accessibility, Best Practices, SEO)
• Works smoothly on recent Chrome, Safari, Edge, and Firefox, both desktop and mobile
• Service worker providing offline caching of critical assets and queued actions for when the user regains connectivity
• Push notifications for upcoming appointments and new consultation messages
• Clean, well-commented source code in a Git repository with clear README and setup scripts
• Brief demo video or live link proving appointment flow, data CRUD, and live video call operate end-to-end

Tech freedom is yours—Redux Toolkit vs. Context, WebRTC libraries, UI frameworks—but keep the stack React-centric and avoid vendor lock-in. If you have previous healthcare or HIPAA-related experience, let me know; otherwise solid web security knowledge is a must.

I’m eager to review proposals detailing timeline, milestone breakdown, and any similar PWAs you’ve shipped.
