I integrate laboratory analyzers with LIS/LIMS and medical devices with HIS/HIMS or EHR/EMR—plus DICOM imaging workflows—with 9+ years of healthcare-integration experience across 1,000+ analyzer and medical-device integrations and 350+ environments. I work with laboratories, diagnostic centers, hospitals, medical-device companies, LIS/LIMS vendors, and healthcare software teams that need reliable connectivity between equipment and clinical systems. If you are dealing with manual result entry, missing results, incorrect mappings, barcode or order problems, unstable device communication, HL7/ASTM errors, TCP/IP or serial-port issues, or an undocumented legacy protocol, I can help diagnose and implement the right solution. 1. Laboratory Analyzer Integration I connect laboratory analyzers and IVD instruments with LIS/LIMS, laboratory middleware, and custom laboratory systems. • Biochemistry and clinical chemistry analyzers • Hematology and coagulation analyzers • Immunoassay and serology systems • Urinalysis and microbiology analyzers • Blood gas and POCT instruments • Veterinary diagnostic analyzers • Unidirectional and bidirectional interfaces • Order download, sample ID, and barcode workflows • Result upload, test-code mapping, flags, and units • QC processing, Calibration, acknowledgements, error handling, and audit logs • ASTM/CLSI, HL7 v2, TCP/IP, RS-232/RS-485, file-based, and manufacturer-specific protocols 2. Medical Device Integration I connect medical and clinical devices with HIS/HIMS, EHR/EMR, LIS, middleware, cloud platforms, APIs, and custom healthcare applications. • POCT and bedside instruments • Vital-sign and patient-monitoring devices • Blood gas and rapid-testing devices • Dialysis equipment • Diagnostic and treatment devices • Device data acquisition and normalization • Patient, order, and result matching • HL7 v2, FHIR, REST APIs, TCP/IP, serial, database, and file-based integration • Legacy device connectivity and proprietary-protocol implementation 3. Medical Imaging and DICOM I support imaging workflows involving CT, MRI, X-ray, ultrasound, RIS/PACS, Orthanc, healthcare APIs, and custom imaging applications. • Modality-to-PACS/RIS connectivity • DICOM workflow implementation and troubleshooting • Orthanc-based PACS integration • Imaging metadata and workflow integration • DICOM-to-API and custom healthcare-system connectivity 🚀Integration and Middleware Development I can support the complete integration lifecycle: • Interface and protocol analysis • Architecture and workflow design • Middleware and connector development • Message parsing, mapping, validation, and transformation • Communication logging, retries, error recovery, and monitoring • Testing with sample messages and real equipment • Deployment, troubleshooting, documentation, and long-term maintenance ⚙️My core technologies include C#, .NET, Python, FastAPI, Delphi, SQL Server, PostgreSQL, MySQL, Oracle, REST APIs, socket programming, HL7, ASTM, DICOM, FHIR, and Mirth Connect. To assess your project, send me: 1. Device or analyzer manufacturer and model 2. Interface manual, protocol specification, or DICOM conformance statement 3. Sample messages, result files, screenshots, or communication logs 4. Target LIS/LIMS, HIS/HIMS, EHR/EMR, RIS/PACS, API, or custom system 5. Required workflow: orders, barcodes, results, images, QC, Calibration or device data I will review the information and recommend a practical integration approach.
