In late 2025, a Series A health-tech startup in San Francisco approached us with an ambitious goal: build a full telemedicine platform — iOS app, Android app, provider dashboard, and backend — in under 16 weeks, fully HIPAA compliant, with a budget of $85K.
We shipped it in 14 weeks. It launched with a 4.8-star App Store rating and onboarded 25,000 patients in the first 6 months.
The Challenge
HealthSync needed to support three user types: patients (booking, video calls, prescriptions), providers (schedules, consultations, prescriptions), and admins (monitoring, compliance reporting).
Non-negotiable requirements: HIPAA compliance, HD video calling with screen sharing, e-prescription integration, and AI-powered symptom triage.
Tech Stack Decision
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, reducing provider assessment time by 40%.
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.
Timeline Breakdown
Weeks 1-2: Discovery, architecture, HIPAA planning, Figma prototypes.
Weeks 3-6: Core backend, React Native app shell, provider dashboard.
Weeks 7-10: Video calling, e-prescriptions, AI triage, push notifications.
Weeks 11-12: QA, HIPAA pen testing, performance optimization, App Store submission.
Weeks 13-14: Beta bug fixes, final compliance review, production launch.
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.
