Senior Python Engineer at Cardinal Health who modernized healthcare platforms and built clinical AI workflows.

At Cardinal Health, I led development of HIPAA-compliant EHR and claims-processing platforms, including secure workflows for scheduling, billing, and clinical data. I also migrated core services to Python with FastAPI and Django REST Framework and helped move a monolithic application to microservices.

I integrated LLM-based clinical workflow assistants for chart summarization and medical-coding suggestions, and developed NLP pipelines that mapped medical entities to healthcare standards. Earlier, I worked on healthcare systems at ComResource and payment-processing solutions at JPMorganChase.
