A Kodjin FHIR-centric data platform for digital health

Kodjin was born out of the challenge of designing and implementing a national-scale, centrally managed HIE (health information exchange) capable of supporting 40 million users and storing data as fine-grained, RESTful resources.

The result was one of the few global FHIR servers, adopted by major organizations and IT vendors.
Today, it has evolved into a full-featured health data platform.

External EHRs

Wearable devices

Internal data sources

Ingest data in any format from multiple sources

Data acquisition & transformation

Data Mapper

Effortlessly creates templates to map HL7v2, C-CDA, and custom data formats to FHIR.

ELT Solution

Extracts, transforms, validates, and loads proprietary data into FHIR, HL7v2, and other medical formats within our FHIR platform.

Advanced FHIR Validator

Profile-level checks ensure structural, semantic, and terminology compliance.

Transform, standardize, and validate raw data

Data storage & processing

FHIR Server

Offers secure data storage and transaction processing through a powerful low-code toolset and RESTful API. This FHIR software is built on a microservice event-driven architecture in Rust for exceptional performance.

Terminology Service

Manages and standardizes healthcare codes like ICD-10, SNOMED CT, LOINC, and RxNorm, allowing users to upload, search, and navigate codes through an intuitive terminology browser.

Rust CLI App

A developer portal for task management.

Store, process, and secure structured data

Regulatory-ready interoperability

Patient Access API

Lets patients / members securely access their health records.

Provider Access API

Shares member claims and clinical data with treating providers.

Payer-to-Payer API

Transfers claims, clinical history, and prior auth between health plans.

Prior Authorization API

Enables ePA requests, responses, and status updates, supporting workflow automation.

Share, exchange and run apps on high-quality and AI-ready data

Data activation & AI enablement

FHIR data Materialization Layer

Reshapes FHIR data into longitudinal, semantically enriched, and analytics-ready structures that AI can reason over.

Conversational FHIR Analytics

Delivers on-demand insights, enabling practitioners and managers to access data views using an AI assistant that translates between human language and SQL.

Make your data accessible to your team and put it to work in daily operation

BI tools

SMART on FHIR apps

AI-powered health apps

Connect any type of data-consuming tools bi-directionally

Access Control

Provides a universal security layer for all FHIR interactions, including machine-to-machine connections, legacy integrations, and enterprise identity systems.

SMART on FHIR Access

Delivers a dedicated security layer for SMART on FHIR applications, enabling user authorization, authentication, making it a secure FHR-compliant interoperability solution with easy integration into existing client security systems.

Our Kodjin Data Platform works as a holistic solution with interconnected modules, or you can apply individual products for specific tasks. Some are useful beyond FHIR-based projects, like ELT and Terminology Service.

Major use cases for our FHIR Data Platform

A foundation for FHIR-compliant HIE systems

Accelerate custom HIE development by months with a ready-to-use, scalable FHIR platform that provides data processing, integration, transformation, and security layers, along with built-in analytics. Just add any custom health operation automation and solution administration modules.

A foundation for enterprise data fabric

A comprehensive data management and analytics platform, streamlining data governance, clinical insight extraction, trial recruitment, and observational research. Can serve as a clinical data repository. It’s a complete ready-to-use FHIR solution requiring only integration setup and pipeline configuration.

A foundation for custom FHIR-native and AI-powered applications

Kodjin FHIR platform can serve as a headless core for data management, analytics, AI products, or modern EHRs, CDSS solutions, easily customizable for your unique market value. It’s also an optimal backend for applications that work with diverse data sources, large datasets, or require various integrations.

A FHIR solution for product transformation

You can make your commercial or custom product better aligned with modern FHIR-compliant interoperability practices without legacy software modernization. We’ll integrate our product seamlessly, without adding extra load on your existing system.

A solution for data exchange regulatory compliance

We help health IT products, payers and healthcare organizations meet interoperability regulations, including ONC, CMS, IPS, ISiK, and MedMij, with seamless FHIR-native software integration, ensuring compliance now and in the future.

We’ve got you covered from Kodjin implementation to ongoing support

Edenlab will manage the platform implementation, including connector setup, pipeline configuration, data mapping, and export, along with developing custom features to ensure your product or platform is fully integrated into real-world environments and your business strategy.

What sets Kodjin apart

Scalable and high-performing

Our FHIR data platform efficiently processes millions of patient records. Load tests showed up to 920 RPS for GET requests, 694 records/sec for bulk import, and 1 million resources exported in 201 sec, ensuring fast and reliable data exchange.

Based on modern technology stack

Kodjin leverages a Rust-based architecture, with an event-driven, microservices approach for real-time processing. It utilizes MongoDB, PostgreSQL, ClickHouse, and Redis for flexible and optimized data storage and analytics.

Focused on data quality

Our FHIR- compliant solution ensures accurate, standardized, and interoperable healthcare data. It validates, transforms, and normalizes records using proprietary Data Mapper, ELT, and Terminology Service, eliminating data inconsistencies.

Infrastructure-agnostic

Kodjin supports deployment across any environment, including AWS, GCP, Azure, or on-premises. It leverages Infrastructure as Code (IaC) for scalable, automated infrastructure management, ensuring consistency and flexibility.

Designed for maintainability

Kodjin is built for easy and cost-effective maintenance with a low-code approach, allowing quick updates. Its modular architecture makes ongoing adjustments seamless without additional development.

Independently supported

We ensure a smooth ownership and knowledge transfer, empowering your team to independently manage the solution. We make it easy to handle ongoing operations without relying on external support.
