Medical Imaging & Clinical Workflows:

• Core Full-Stack Developer on a cloud-native RIS/PACS platform, building a zero-footprint web DICOM Image Viewer using React and Cornerstone3D for radiology diagnostic workflows.

• Ported complex clinical workflows, such as Series Splitter and Mammography Sorting, from a legacy Delphi desktop app

• Developed advanced diagnostic tools including ROI/SUV analysis and Automatic Window Leveling

Performance & Scalability:

• Optimized large-study performance through progressive retrieval, Web Worker caching, and prefetching, improving load time and reducing memory usage.

System Architecture & Backend Services:

• Migrated Image Viewer from v1 → v4, redesigning architecture for performance and long-term maintainability.

• Architected a Node.js microservice for generating DICOM Structured Reports (SR) from raw measurement data, closing a key gap in the clinical study export pipeline.

• Built DICOMweb and FHIR APIs using .NET 8 to support clinical data pipelines, leveraging Azure services including Functions, Event Grid, Blob Storage, Cosmos DB, Key Vault, and MS SQL.

Testing & Engineering Practices:

• Resolved P1/P2 production incidents and conducted root cause analysis (RCA) and post-mortems that improved system reliability and reduced recurring failures.

• Developed automated tests including unit, integration, and Playwright-based E2E tests for critical Image Viewer workflows, improving system reliability and release confidence.

• Mentored junior developers and reviewed frontend PRs, improving team code quality and technical decisions.
