Senior Full-Stack Developer · Healthcare Platforms

I build production healthcare systems that ship, scale, and stay maintainable.

From DICOM/PACS backends to React frontends and cloud infrastructure, I deliver end-to-end products for teams that need reliability under real-world constraints.

Built and modernized systems across medical imaging, data pipelines, and multi-team frontend platforms.
