BigHeart Technical Specifications

The BigHeart platform is a comprehensive information system built on modern technologies and approaches with the aim to deliver a maintainable, flexible, and scalable system. The heart of the system is the microservice architecture built on SOLID principles. 

There are 5 main system components:

Customer-facing applications: WLA configuration supported

• Web Application: React SPA, Ant design system + custom components, Automated UI testing via Cypress Framework
• Native iOS Application: SWIFT 5, SWIFT UI, Automated UI testing via XCTest Framework
• Native ANDROID Application: Kotlin 1.8, Material Design UI Kit, Automated UI testing via Maestro Framework

Backoffice applications

• Admin Console: React SPA, Ant design system + custom components, Automated UI testing via Cypress Framework
• EHR portal: Angular 15 (upgrade to 16 in progress) SPA, Ant design system + custom components, Automated UI testing via Cypress Framework

Business Intelligence

• BI Engine: Power BI
• ETL & Data Warehouse: Databricks 

Integrations

• SFTP integration: Secure data sharing
• REST API/Webhooks: We generate OpenAPI specification or Postman collection on demand
• Support for Standard Implementation Formats (In Preparation): HL7, FHIR, USDCI, TEFCA

Backend: 

• NodeJs backend: Node 20.14.0 (current LTS) + MongoDB Atlas 5. Consists of microservice architecture with asynchronous internal messaging system (AMQP)
• Rails backend: Rails 7.1 + PostgreSQL (AWS Aurora), in process of migration to NodeJs. Primarily responsible for handling content and management of events
• BigMarker: Video conference platform. WebRTC with encrypted transmission and no software downloads. Video coding, recording, and compression format: H264. Internet bandwidth: Minimum of 2Mbps for attendees and 10 Mbps for hosts, presenters, and anyone who wants to share their microphone and camera.

Supported Systems

• Web access via the latest version of Chrome (strongly recommended) or Firefox (strongly recommended), Opera, Safari, Edge. Operating Systems Supported: Windows 10 or later, Mac OS X 10.0 or later, or Linux RHEL 5.6 or later, openSUSE 11.3 or later, or Ubuntu 10.04 or later
