The Challenge
A Series A health-tech startup in San Francisco needed a full telemedicine platform — iOS app, Android app, provider dashboard, and backend — in under 16 weeks, fully HIPAA compliant.
Our Solution
React Native for mobile (client's future team was JS-based). Node.js + Express on AWS for backend. Twilio Video (HIPAA-eligible) for video calls. Next.js for the provider dashboard. OpenAI API for AI triage — routing patients to the right specialist.
Architecture Highlights
HIPAA compliance from day one. AES-256 encryption at rest, TLS 1.3 in transit, role-based access control, audit logging on every data access.
Offline-first scheduling. AsyncStorage with a sync queue for patients in rural areas with spotty connectivity.
Sub-second video connection. Pre-initialized Twilio rooms 30 seconds before appointments for near-instant connection.
Results
25,000 patients in 6 months. 4.8★ App Store rating. 340% user growth month-over-month. 40% reduction in consultation time. Zero HIPAA incidents. The client raised an additional $4M in funding.
