The Challenge: Secure, Real-Time Medical Consultations
Building an online medical support platform is not just about video calls; it's about trust, compliance, and absolute reliability. We developed a multiservice ecosystem that enables seamless patient-doctor consultations, supporting both high-quality peer-to-peer sessions and complex group conferences via VoIP and WebRTC technology.
What Was Built
The project required a total orchestration of media flows and secure data handling. We engineered a resilient infrastructure on AWS, ensuring that every consultation meets the highest standards of quality and privacy.
Distributed Multiservice Backend Developed with NestJS and Node.js, managing complex scheduling, patient records, and session signaling with high reliability.
Real-Time Communication Layer Integrated WebRTC and Twilio to support 100k+ simultaneous meetings, managing participant media devices for optimal call quality.
Infrastructure as Code (IaC) Full orchestration of the AWS ecosystem using Terraform, enabling automated, repeatable, and secure environment provisioning.
Security & HIPAA Compliance Implemented advanced cryptography and industry-leading security practices to achieve full HIPAA compliance for patient data.
Supported By Technology Stack
My Role & Responsibilities
As Team Lead and Tech Lead, I was responsible for the technical direction and the growth of the engineering team, acting as a full-stack architect across the entire ecosystem.
- Architecture Improvement. Redesigned core components to handle massive concurrency and complex medical workflows.
- Core Development. Led the development of mission-critical services and real-time media handling modules.
- Team Leadership. Built and mentored a high-performing team of 18, establishing rigorous code standards and inspection processes.
- Process Engineering. Established robust CI/CD pipelines and automated testing frameworks to ensure zero-regression delivery.
- Performance Optimization. Optimized database queries and media flows to support 100k+ simultaneous sessions.
Major Achievements
- Massive Scale: Successfully supported 100k+ simultaneous ongoing meetings with over 230k total members.
- Healthcare Integration: Seamlessly integrated with major US medical systems and provided service for hospitalities.
- Secure Data Management: Implemented role-based permissions and advanced encryption to protect sensitive medical data.
- HIPAA Compliance: Achieved and maintained full HIPAA certification through rigorous security auditing.
Lessons Learned & Practical Takeaways
Security as a Foundation. In healthcare, security is not a checkbox—it's the core product. Advanced cryptography and HIPAA standards must be baked into the architecture from day one.
Media Orchestration Complexity. Handling 100k+ simultaneous video sessions requires deep observability. Managing participant media devices is as much about UX as it is about engineering.
Team Scaling Culture. Mentoring a team of 18 requires strong processes. Code inspection and shared ownership are critical when building mission-critical medical systems.
