• Build and ship production AI & automation systems for healthcare — end-to-end pipelines (Python, Playwright, Selenium) that extract, validate, and synchronize clinical, resident, and demographic data into SQL Server, with logging, reconciliation, and error recovery.
• Developed an AI clinical decision-support platform that turns CMS MDS assessments into interactive dashboards, compliance findings, and reimbursement insights (HIPPS/PDPM) for skilled-nursing facilities via automated PDF extraction and deterministic, guideline-aligned rules.
• Built Generative AI applications — LLM document-analysis assistants with multi-provider routing (OpenAI, Claude, Gemini), RAG, and validated structured output — plus a FastAPI eligibility-verification service with async batch processing, Dockerized deploys, and CI/CD.

• Delivered end-to-end web applications — including a Hospital Management System and e-commerce platforms — with Python, Django & DRF, and responsive HTML5/CSS3/JavaScript/Bootstrap frontends.
• Built RESTful APIs and backend services, integrated third-party APIs, and collaborated cross-functionally on requirements, design, and testing.
