About Me

I am a Full Stack AI Engineer and CS student focused on integrating clean system architecture with auditable AI reasoning. My experience spans from designing robust REST APIs and data models to building retrieval-augmented generation and agentic workflows. I prioritize keeping AI-assisted decisions human-reviewed rather than fully autonomous, creating reliable, production-ready systems that solve real-world problems.

AI Clinical Intelligence Platform

★ Featured
📅 Governed Clinical Decision Support System👤 Full Stack AI Engineer

Splits the system into a Node.js/Express service (auth, RBAC, PostgreSQL/Drizzle, governance state machine) and an internal-only FastAPI service running an XGBoost model and a RAG/LangChain pipeline. Requires practitioner review and a CMO/Admin approval gate before any AI-generated recommendation reaches a patient record.
