National E-Health system
The project involves development of the Ukrainian national health system to ensure the availability of high-quality medical data in real time through REST API. The system employs electronic digital signatures and blockchain-like algorithms to ensure data integrity and security.
It’s one of the world’s largest HL7 FHIR-based projects in production, with over 32 million users. The system was built to meet the high-load demands (1 000 RPS current system load).
