Build Router Layer for AI Islamic App (RAG + Multi-Module System)

Project Description:
I have already completed Milestone 1 of my project (Islamic RAG system using Quran/Hadith data with strict output control).
Now I need a developer to implement the Router Layer (Control System) before the existing /ask endpoint.
This is a lightweight but critical component that will route user queries to the correct module.
--------------------
Scope of Work:
1. Build Query Router
When a user question comes in, classify it into one of the following modules:
• islamic_rag
• zakat_module
• halal_scan
• prayer_times
• qibla_compass
• general_chat
--------------------
2. Routing Logic
Based on classification:
• If islamic_rag→ apply query normalization→ send to existing RAG /ask endpoint
• If zakat_module→ do NOT send to RAG→ trigger zakat flow (placeholder logic is fine for now)
• If halal_scan→ trigger halal scan module (placeholder)
• If prayer_times→ trigger prayer time API (placeholder)
• If qibla_compass→ trigger compass module (placeholder)
• If general_chat→ send to general assistant (can be simple for now)
--------------------
3. Query Normalization Layer (Important)
Before sending to Islamic RAG, normalize queries to improve retrieval.
Examples:
• angry → anger
• mad → anger
• interest → riba
• usury → riba
• charity → zakat sadaqah
• donation → sadaqah
• washing before prayer → wudu
• fasting month → Ramadan fasting
--------------------
4. Integration
• Integrate router with existing backend
• Ensure correct module is triggered
• Maintain current RAG behavior (no hallucination, fallback “I don’t know”)
--------------------
Tech Stack (current):
• Python (FastAPI backend)
• Existing /ask endpoint already working
• JSON-based response
--------------------
Deliverables:
• Working router layer
• Query classification logic
• Query normalization implementation
• Proper routing to modules
• Basic testing with sample queries
--------------------
Timeline:
1–2 days
--------------------
Budget:
₹1,000 – 3000 INR
--------------------
Important Notes:
• This is NOT a full system build
• Only router + preprocessing + integration
• Clean, simple, scalable code expected
• Future work available (Zakat module, Halal scanner, etc.)
--------------------
To Apply:
Please mention:
• Your approach (rule-based or AI classification)
• Similar experience (if any)
• Estimated time
--------------------
This is part of a larger AI Islamic assistant project (HalalyAI).
Looking for someone reliable for ongoing work.
