HealthTech Telehealth Platform & Patient Portal

Project Context & Business Overview

A healthcare provider network required a centralized, secure telehealth platform enabling patients to book virtual appointments, consult with specialized physicians via encrypted video calls, and access lab results securely on mobile and desktop.

The Problem & Operational Inefficiencies

01.

Patients faced clunky appointment scheduling requiring phone calls and manual confirmation.

02.

Fragmented consultation records caused communication gaps between referring doctors and specialists.

03.

Strict data privacy standards mandated end-to-end encryption for all medical records and video streams.

Core Engineering Requirements

  • End-to-end encrypted video consultation using WebRTC with automatic bandwidth adaptation.
  • Granular role-based access controls for doctors, patients, receptionists, and lab technicians.
  • Automated appointment reminders via SMS and WhatsApp to reduce patient no-show rates.
  • Secure document repository for medical histories, prescriptions, and lab diagnostic PDFs.

The Architectural Solution

Developed a responsive web platform using React and TypeScript with WebRTC peer-to-peer encrypted communication protocols.

Constructed a secure Node.js backend with AES-256 encrypted database columns for all Personally Identifiable Information (PII) and medical histories.

Integrated automated WhatsApp Business notification workflows for instant booking confirmations and prescription download links.

Key Features & Capabilities Delivered

Peer-to-Peer Encrypted Video Consultations

Browser-based video calls with adaptive bitrate streaming that functions reliably even on unstable cellular connections.

Digital Prescription Generator

Allows doctors to select medications from a standardized pharmacopeia, generate signed digital PDFs, and dispatch directly to patients.

Automated WhatsApp Reminders

Scheduled consultation notifications dispatched at 24 hours, 2 hours, and 10 minutes prior to call time.

Key Implementation Details

💡 Configured TURN relay servers across multiple geographic regions to eliminate call connection drops behind strict hospital firewalls.
💡 Enforced multi-factor authentication (MFA) via time-based one-time passwords (TOTP) for all clinical staff accounts.

Engineering Learnings & Takeaways

Patients require zero friction to join telemedicine calls; requiring native app downloads creates severe drop-off compared to browser-based WebRTC.

WhatsApp is the most reliable notification delivery channel in the Indian and Southeast Asian markets, vastly outperforming email.
