A developer has detailed the architecture and challenges of building a Financial Document Intelligence Platform that allows users to query bank statements in natural language. The system uses a microservices approach with FastAPI and Flask, integrating LLMs for natural language understanding. Key challenges addressed include preventing UI freezes during heavy data extraction, mitigating LLM hallucinations by using retrieval-augmented generation (RAG) where the LLM generates SQL queries rather than answers, and handling diverse bank statement layouts through a hybrid parsing approach combining regex heuristics and LLM vision.
