Hi, I'm Justin πŸ‘‹

Applied AI Engineer | HealthTech Domain Expert

I build production LLM agent systems and agentic RAG pipelines for healthcare. 9+ years as an Emergency Room Technician β€” I don't just engineer AI for healthcare, I understand it from the inside.

πŸš€ Featured Projects

πŸ«€ CardioBot β€” AI Clinical Cardiology Assistant

Multi-LLM agentic RAG system for clinical cardiology support

  • Architecture: LangGraph state machine routing queries across Claude Sonnet, Gemini Vision, and GPT-4
  • RAG Pipeline: 895 indexed passages from the 2023 ESC ACS Guidelines in ChromaDB
  • Features: Clinical Q&A, EKG image interpretation, weight-based drug dosing, citation search

πŸ₯ Why HealthTech AI?

I spent 9+ years as an Emergency Room Technician at a Level II trauma center β€” performing EKGs, monitoring critical patients, and working alongside ER physicians on ACS and STEMI cases. I've seen firsthand where clinical workflows break down and where AI can genuinely help.

That domain expertise is built into everything I build.
