Elder Companion Web App Development

I’m creating an easy-to-use ride-style web application that lets senior citizens tap one dedicated button to request a vetted companion. The request should instantly reach nearby companions who can accept or decline, after which both parties see one another on a live map with real-time location tracking. The same map must remain fully responsive so it feels native on mobile phones yet stays comfortable to read on a desktop browser.

Key elements I need you to build and wire together:
• Secure sign-up / login for elders and companions
• One-click “Request Companion” button that triggers the workflow described above
• Companion dashboard to accept or reject incoming requests
• Live map module (Google Maps or similar) with continuous real-time tracking of both users during the session
• Razorpay integration for seamless in-app payments once a service ends
• Automatic notifications: SMS and/or email for every critical state change (request placed, accepted, companion arriving, payment confirmation)

All components should be coded with scalability in mind (modern JS framework on the front end, clean API layer, and a lightweight admin panel). Please outline your proposed tech stack, estimated timeline, and any prior mapping or payment-gateway projects you can reference.

I will provide UI wireframes and brand assets after we start; you deliver the complete working web app, well-documented code, and a brief hand-over session so my team can maintain it.
