ELLKAY Tech Stack

Healthcare data connectivity platform for EHR/lab/payer ecosystems

Software Development Elmwood Park, New Jersey 501–1,000 employees Founded 2002 Privately Held

ELLKAY operates a healthcare data management and interoperability platform serving hospitals, labs, payers, and EHR vendors since 2002. The tech stack reveals dual momentum: heavy HL7/FHIR/Epic/MEDITECH expertise (legacy healthcare integration work) paired with modern cloud adoption (AWS, Azure, GCP) and streaming data infrastructure (Snowflake, Apache Airflow, dbt, Azure Data Factory). Active projects center on cloud migration and API-driven data exchange, while pain points highlight the core operational challenge — managing massive transaction volumes across complex legacy integrations while modernizing toward cloud-native architectures.
