PROJECT CONTEXT
I have already built a production-ready Legal AI web application with a full RAG architecture.

It is deployed and working.
Current stack:
Frontend

Vite

Backend

Database

Row-Level Security for strict multi-tenant isolation
AI & Retrieval
Hybrid search (vector + keyword)
Reciprocal Rank Fusion
Cohere reranking
Voyage AI legal embeddings
NVIDIA NIM (Qwen 235B) for generation
Multi-layer legal-aware chunking
Query classification and cost optimization
The architecture is complete.
The backend is stable.
The RAG pipeline is working in production.
Now I need to expand this into a mobile app.
YOUR ROLE

Connect it properly to the existing backend APIs
Design clean scalable mobile architecture
