Description: I’m seeking a skilled developer to build a secure, HIPAA-compliant middleware MVP to integrate Ensora Health (EHR) with QuickBooks Online, eliminating manual data entry for my audiology practice. The focus is robust API integration, with a simple React-based patient check-in hub to replace JotForm. The architecture must be modular for future add-ons (e.g., Google Calendar, iFax, reporting). What I Need: API Integration: Build RESTful endpoints in Node.js (preferred) or Python to sync patient demographics (name, DOB, insurance), billing data (CPT codes, charges), and invoices bidirectionally between Ensora’s Echo API and QBO. Real-Time Sync: Use webhooks or polling for automatic updates (e.g., new Ensora patient → QBO customer; appointment → QBO invoice). Patient Check-In Hub: Develop a touch-friendly React form (using Material-UI) for patient check-ins, updating Ensora via API. Database: Use PostgreSQL for sync logs and data transformations, ensuring HIPAA-compliant storage. HIPAA Compliance: Implement encryption (in transit/at rest), audit logging, and role-based access (OAuth/JWT). Must sign a BAA. Deliverables: Scalable codebase, setup instructions, Postman/Swagger examples, unit tests, and CI/CD pipeline (e.g., GitHub Actions). Scalability: Design an event-driven architecture (e.g., BullMQ queues) to support future integrations (Google Calendar, iFax, Word templates). What You Bring: 3+ years building API services with Node.js (Prisma, Express) or Python (Flask/FastAPI). Experience with Zapier-style syncs or EHR integrations (e.g., Epic, Ensora, QBO). Familiarity with React and Material-UI for simple, responsive UIs. Knowledge of HIPAA practices and PHI handling (US-based or formally trained). Bonus: Experience with BullMQ, AWS (EC2/RDS), Docker, or healthcare APIs. Notes: Ensora’s Echo API access will be provided; CSV exports may be a fallback if API is limited. Timeline: 4-6 weeks for MVP. Budget: $6K-$12K (fixed or hourly). To Apply: Share examples of API integrations or sync projects (healthcare preferred). Describe your approach to HIPAA compliance and event-driven systems. Propose a timeline with milestones (e.g., Week 1: setup, Week 3: sync prototype).
