BACKEND SYSTEMS

Health Platform Backend Development

Scalable, secure backend systems that power modern healthcare applications while ensuring HIPAA compliance and data integrity.

THE CHALLENGE

Building Healthcare-Grade Backend Infrastructure

A growing telehealth startup needed to rapidly scale their patient management platform to handle 10x user growth while maintaining strict healthcare compliance and data security standards.

Legacy monolith struggling under load

Single database bottleneck causing 30-second response times

HIPAA compliance gaps

Missing audit trails and encryption standards

No real-time capabilities

Healthcare providers couldn't receive instant patient updates

Backend architecture
OUR SOLUTION

Modern Microservices Architecture

Microservices Migration

Broke monolith into 8 focused services: Patient Management, Scheduling, Billing, Notifications, File Storage, Authentication, Audit, and Analytics.

  • • Python FastAPI services
  • • Docker containerization
  • • Kubernetes orchestration

HIPAA Compliance

Implemented comprehensive security measures ensuring full HIPAA compliance with audit trails and encryption.

  • • End-to-end encryption (AES-256)
  • • Comprehensive audit logging
  • • Role-based access control

Real-time Features

Added WebSocket connections and event streaming for instant updates and real-time collaboration between providers.

  • • WebSocket connections
  • • Redis pub/sub messaging
  • • Event-driven architecture
