I’m building a subscription-driven healthcare ecosystem that seamlessly links patients, doctors, diagnostic labs, and pharmacies across India’s Tier-2 and Tier-3 cities. The core objective is to let every stakeholder operate within clearly defined geographical “zones”, yet remain part of one scalable, cloud-first platform that can grow city by city without code rewrites. Scope of the first release The initial build must cover three mission-critical domains: 1. Patient–doctor communication • Video calls • Text messaging • Phone calls 2. End-to-end lab test booking • Online test selection and slot confirmation • Doorstep or walk-in sample collection scheduling • Results delivery and lifetime results management for both patient and doctor portals 3. Pharmacy integration • E-prescription ingestion, medicine availability check, order placement, refill management, and delivery tracking inside the same app experience Key product expectations • Zone logic: every user signs up within a pin-code cluster so search, availability, and logistics stay local, yet doctors can opt-in to wider coverage tiers. • Multi-tenant architecture: a clean separation of data by zone while sharing core micro-services (auth, payments, notifications). • Subscription engine: monthly and yearly plans, coupon support, proration, and automated renewal reminders. • Mobile-first UX: Flutter, React Native, or similar so one codebase serves Android and iOS; responsive web portal for providers and admins. • Compliance: HIPAA-grade encryption at rest and in transit, role-based access, audit logs, and GDPR-style user data exports. • Third-party hooks: Twilio (or equivalent) for calls/texts, Stripe/Razorpay for payments, popular LIS and pharmacy APIs for downstream integration. • Analytics: zone-wise cohort growth, churn, and engagement dashboards exposed through an admin panel. Deliverables • Functional MVP deployed on a cloud platform of your choice (AWS, GCP, or Azure) with CI/CD pipelines. • Source code repository with clean commit history, unit tests, and API documentation (Swagger/OpenAPI). • Admin manual plus short Loom walkthrough for onboarding my internal ops team. • Post-launch support agreement for the first 30 days to address priority bugs and minor enhancements. Acceptance criteria The MVP will be considered complete when a patient in any configured zone can sign up, purchase a subscription, consult a doctor via all three communication modes, book a lab test with home collection, receive results inside the app, and order prescribed medicines through an integrated pharmacy partner—each flow traceable in the admin dashboard. If the above resonates with your expertise in scalable health tech, I’m ready to review your timeline and tech-stack proposal.
