Maxwell Marich

Senior HL7 Interface Analyst with 5+ years of experience delivering and supporting high-volume healthcare integrations in production environments. Expert in HL7 v2.x messaging (ADT, ORM, ORU, NTE) with a strong specialization in PACS and imaging workflows, enabling seamless data exchange between RIS, EHR, and clinical systems. Experienced in integrating AI-driven outputs into clinical workflows, including ingesting, transforming, and routing results through HL7 interfaces to downstream systems.

Recognized for rapidly diagnosing complex interface issues, strengthening data integrity, and building scalable solutions using Mirth Connect, SQL, and scripting for advanced message transformation and validation. Vast experience with DICOM transmission models and validation. Technically grounded in networking and system infrastructure, with hands-on experience supporting hosted and cloud-based environments across AWS and Azure.

Skilled in API-based integrations, including connecting HL7 order workflows (ORM) to cloud platforms via RESTful services, as well as resolving connectivity and transport-level issues (LLP/MLLP) that impact real-time clinical messaging. Ensures high availability and performance of mission-critical integrations across hybrid environments. Proven leader in interface delivery, driving HL7 standups and coordinating cross-functional teams through full project lifecycles—from build and testing to go-live and production support.
