HealthSync Secure Telehealth Portal
Tech Stack: React Native, Node.js, WebRTC, HIPAA Security, AWS
The Challenge
A private healthcare network needed a secure, HIPAA-compliant mobile application allowing remote biometric sign-ins and instant high-fidelity video consults.
Our Solution
We engineered a native-speed React Native app with biometric FaceID integration, implementing low-latency WebRTC streams, and securing sensitive data packages.
Business Impact & ROI Analysis
Compliance Score
Achieved flawless certification in external compliance verification.
Consultation Capacity
Scaled concurrent sessions from 4,000 to over 12,000.

Engineering Deep-Dive: End-to-End Encrypted WebRTC Architecture & Secure Key Custody
We built a zero-trust media platform where peer-to-peer consulting data is negotiated using a secure signaling server built on Node.js and WebSockets. The video and audio channels are secured using DTLS (Datagram Transport Layer Security) and SRTP (Secure Real-time Transport Protocol). Biometric credentials (FaceID) are verified locally using React Native Key Store hooks, ensuring patient identifiers never leave the device. Medical charts are encrypted using AWS KMS keys using envelope encryption.
Key Architectural Decisions
Technical Takeaways & Lessons Learned
Lesson 1
Biometric credentials verified locally inside the device's secure enclave eliminates cloud-based data breaches entirely.
Lesson 2
WebRTC peer-to-peer connections require robust TURN server fallback clusters to handle strict enterprise firewalls.
Lesson 3
Immutable audit trail logging is essential for pass-fail HIPAA certification cycles.
