WhatsApp-based Medical Records System

@ambar

Cloud API or BSP route? India-only storage required? Single region or DR from start? I went through your description carefully. This is a consent-gated storage system, not a chatbot. Clear. I’d build webhook-based WhatsApp API (Node/.NET). Incoming messages hit a queue first so uploads don’t block question flow. Redis for short session state (consent + metadata steps). PostgreSQL for users + reports. Files stream directly to object storage. No local disk. Server-side encryption + separate KMS key. Also app-level AES before upload (extra layer). Strict MIME recheck, not just extension. Async virus scan before marking report active. Auto-clean orphan uploads if metadata not finished. Rate limit per number. Basic abuse shield. Immutable consent log (append-only table). Retrieval via indexed date/type/hospital + normalized keyword column (simple match, not AI). Signed URL 10 min. Forced download header. HTTPS only. DELETE ALL = hard delete storage + DB + audit tombstone. Permanent wipe. I’ve done similar structured WhatsApp automation before: One open thing — should DELETE ALL require second confirmation keyword? Yes or No?

A consent-first medical record vault over WhatsApp — that’s a sensitive build, and I appreciate how clearly you’ve defined the non-negotiables. From your flow, this isn’t a chatbot. It’s a secure document pipeline: strict YES-based consent gate, minimal identity (mobile only), sequential profile creation, encrypted file storage, metadata tagging, and controlled retrieval using signed, time-limited links — with permanent delete support and full logging. I’ve worked on backend systems where data privacy, audit logs, and role-based logic were core requirements. I’m comfortable building webhook-driven WhatsApp flows with strong validation layers, encrypted object storage (S3-compatible), metadata indexing, and secure signed URL generation. The consent gate and “ignore unless YES” rule would be enforced at middleware level so it’s technically non-bypassable. I’d structure this as: Node.js backend (Webhook + rules engine) PostgreSQL for metadata + consent logs Encrypted S3 storage WhatsApp Business Cloud API Strict validation + rate limiting Estimated timeline: 1–2 weeks. Budget: ₹35,000 fixed. Maintenance: minimal monthly cloud + monitoring. Do you already have WhatsApp Business API approval, or should that be included in scope?

I made similar secure document storage systems over WhatsApp and webhook-based messaging APIs, and I can share architecture flow + security model details with you in DM. Hi, Your requirement is very clear — this is NOT a chatbot, but a consent-first, privacy-focused medical document vault over WhatsApp. That distinction is critical, and I fully understand the compliance sensitivity here. I have experience building: • Secure document pipelines • Encrypted cloud storage architectures • WhatsApp webhook automation systems • Consent-gated workflows • Healthcare-adjacent systems with strict data boundaries Below is how I would design and implement your system.
