Architecture
Layered services with an isolated AI workflow.
MediLink uses an Angular SPA connected to a Spring Boot application API.
The backend manages business logic, persistence and security while communicating with an independent FastAPI AI service and external integrations.

Retrieval-augmented guidance,
structured for safer interpretation.
The AI component runs as an isolated FastAPI service using a medical RAG pipeline. Relevant medical context is retrieved from a FAISS vector store before a Groq-hosted language model produces a structured response.
