Alexander K.

Healthcare Software Developer | AWS, DICOM, PACS, Orthanc, OHIF

Background: I’ve worked across major EMR platforms (frontend architecture, healthcare data pipelines, compliance-critical systems), biomedical R&D (production AI segmentation for radiology, GPU cluster deployment), and hospital-facing healthcare IT (PACS infrastructure, medical equipment integration). What I do: DICOM/PACS systems (routing, migration, Orthanc+OHIF integration), cloud medical imaging (AWS-based PACS with HIPAA-aware PHI handling), AI in clinical workflows from model to production deployment, legacy modernization with zero-downtime strategies, and AI-augmented development — I use Claude Code and MCP integrations daily in production healthcare work. Recent work: a horizontally-scalable DICOM routing platform with HAProxy failover, validated through load testing and client production deployment; cloud PACS deployment (Orthanc + S3 + OHIF) with automated PHI detection; real-time AI segmentation deployed on hospital GPU infrastructure. Stack: Python/FastAPI, Orthanc, OHIF, pydicom, React/TypeScript, PostgreSQL, Redis, Docker, AWS, Kafka. I’m direct, detail-oriented, and I ask clarifying questions before starting work. If you’re not sure whether your project needs a DICOM specialist — message me, I’ll tell you honestly.
