Version 1 Demo: Healthcare AI Microservices Prototype + Roadmap for Version 2 🚀

I’ve worked for several companies in healthcare, and in my most recent work, I’ve been deeply engaged in AI + healthcare projects. Healthcare + AI is incredibly powerful, so I’m going to build something special based on my experience.

Version 1 Demo:

Microservices-based RAG system that ingests patient data, embeddings notes, medications, labs, and generates AI answers.

Demo uses sample/fake patient data to explore how AI can help care teams quickly access information and reduce repetitive administrative tasks.

Architecture Diagram (Version 1):
         +-------------------+
         |  Care Staff / User |
         +---------+---------+
                   |
                   v
         +-------------------+
         |    API Gateway    |
         |   (/query endpoint) |
         +---------+---------+
                   |
                   v
         +-------------------+
         |     AI Service    |
         |   (LLM + RAG)    |
         +---------+---------+
                   |
                   v
         +-------------------+
         | Vector Search DB  |
         | Postgres + pgvector |
         +---------+---------+
                   ^
                   |
         +-------------------+
         |    Data Service   |
         | FHIR JSON / Sample|
         | Patient Data      |
         +-------------------+
Version 2 Roadmap (short-term plan):

Integrate real FHIR APIs (sandbox / test server)

Multi-patient and multi-user support with role-based access

Advanced AI: note summarization, medication & lab alerts

Workflow automation: reminders, follow-ups, actionable suggestions

I’m still experimenting with what the ultimate demo will become, but my goal is to solve real pain points in healthcare workflows and demonstrate the potential of AI in healthcare operations.

Looking for feedback, suggestions, or collaborations!

How would you improve the demo?

Are there any workflow challenges in healthcare AI you’d like to see addressed?

Thoughts on making this attractive to recruiters and investors?

Any feedback, thoughts, or ideas are highly welcome. Let’s make something impactful together!
