We designed and implemented a middleware platform that standardizes communication between multiple Electronic Health Record (EHR) systems and a healthcare payment platform. By abstracting vendor-specific logic into a unified integration layer, the solution provides a single point of connectivity for diverse EHR systems. This architecture simplifies integrations, improves maintainability, enhances scalability, and enables faster onboarding of new healthcare providers while ensuring reliable payment processing and standardized data exchange.

Features

• Unified Integration Layer: Standardizes multiple EHR systems through a single API.
• FHIR-Based Data Exchange: Enables secure and standardized healthcare data transfer.
• Real-Time Payment Synchronization: Retrieves balances and updates payments within seconds.
• Caching & Performance Optimization: Minimizes dependency on live EHR calls to improve response times.
• Retry & Audit Mechanism: Maintains data consistency through retries, validation, and comprehensive logging.

Technical Challenges

• Multiple EHR systems with different data formats : Built a unified abstraction layer to standardize data across all integrations.
• Heavy dependency on real-time EHR APIs : Implemented caching and fallback mechanisms to improve performance and availability.
• Scalability and maintenance complexity : Centralized integration logic within a single middleware platform to simplify expansion and maintenance.
