The Challenge

Healthcare integration shouldn't require a team of specialists. Yet every developer trying to connect to EHRs faced months of learning curves, expensive consultants, and enterprise vendors who didn't understand modern development.

  • 1Healthcare integration required deep domain expertise most developers lack
  • 2FHIR and HL7v2 standards are complex and poorly documented
  • 3Existing tools were enterprise-focused with 6-figure price tags
  • 4Testing integrations required access to expensive EHR sandboxes

Modern Cloud Architecture

Tech Stack

TypeScript
Node.js
GraphQL
PostgreSQL
Redis
Kubernetes
AWS Lambda
Terraform

Architecture Highlights

  • Serverless architecture for infinite scalability
  • Multi-region deployment for < 50ms latency globally
  • Event sourcing for complete audit trails
  • GraphQL API for efficient data fetching
  • Kubernetes-based microservices
  • Real-time webhooks for event-driven integrations

Developer Experience First

// Connect to any EHR in minutes, not months
const retrohook = new Retrohook({ apiKey: 'your-api-key' });

// Send patient data in simple JSON
const patient = await retrohook.patients.create({
  firstName: 'John',
  lastName: 'Doe',
  birthDate: '1980-01-01',
  mrn: '12345'
});

// Retrohook handles all the complexity
// ✓ FHIR Resource generation
// ✓ HL7v2 message formatting
// ✓ EHR-specific requirements
// ✓ Error handling & retries

Building for the Future

Open Source First

As a non-profit, we're committed to open-sourcing our tools and building in public. Healthcare needs more collaboration, not more walled gardens.

AI-Powered Mappings

We're using LLMs to automatically generate data mappings between different healthcare standards, reducing integration complexity even further.

Global Healthcare Standards

Expanding beyond US standards to support international healthcare systems and enable truly global health data exchange.
