+# Production-Ready Medical AI Assistant
+
+**Author:** Precious T.
+
+---
+
+## Project Overview
+This project builds a medical AI assistant using **Python**, **FastAPI**, **Tavili**, **Gemini**, and **LangChain**.  
+It’s designed to answer patient questions, suggest possible diagnoses, and pull in evidence-based info from trusted APIs.  
+The system is modular and ready for use in a real-world production environment.

+## ⚙️ Main Components
+
+### FastAPI Endpoints
+- `POST /ask` – Accepts user medical questions  
+- `GET /history` – Retrieves past conversations  
+- `POST /feedback` – Collects user feedback for ongoing improvements  
+
+### LangChain Integration
+- Uses prompt templates to structure medical queries  
+- Keeps conversation context with memory  
+
+### Gemini Model
+- Core language model generating answers  
+- Fine-tuned specifically for safe medical information  
+
+### Tavili Vector DB
+- Stores trusted medical documents  
+- Allows semantic search to enrich answers with relevant knowledge  
+
+### Security & Compliance
+- Basic authentication and API key protection  
+- Designed to handle data carefully, similar to HIPAA standards (no logging of personal health info)  
+
+---
+
+## Implementation Plan
+
+- Build the FastAPI structure and endpoints  
+- Connect LangChain and Gemini for answering questions  
+- Integrate Tavili for knowledge retrieval and context handling  
+- Add authentication, logging, and deploy to production  
+
+---
+
+## Deployment
+- Package the app using **Docker**  
+- Deploy securely to platforms like Render or Heroku with **HTTPS**  
+- Manage secrets through environment variables

+
+## Current Status
+Due to a power outage, I’ve completed the architecture and design so far.  
+Full code will be pushed as soon as power is back.  
+I’m also open to teaming up with a teammate tonight to speed things along.
