I built DocuMind — a financial document automation platform for Chartered Accountants

One thing I noticed while working on financial-document workflows was that a lot of a CA's time can go into repetitive document processing rather than actual professional decision-making.

So I started building DocuMind — a tool designed to automate the repetitive parts of working with financial documents.

💡 The idea

A CA uploads a financial document such as a bank statement, and DocuMind handles the mechanical processing:

Document → Extraction → Normalization → Transaction Processing → Rules → Validation → Structured Output → Excel

Instead of manually going through large documents and preparing the same data repeatedly, the system converts the information into structured, usable outputs.

What I built:

- PDF/document extraction

- OCR for scanned documents

- Transaction extraction and normalization

- Python-based rule processing engine

- Data validation and reconciliation

- Automated Excel generation

- Database-backed document management

- Authentication and user-level document access

- RAG/AI assistant architecture for document Q&A

- Local AI support through Ollama for privacy-sensitive workflows

- React frontend + FastAPI backend

Architecture:

React Frontend ↓ FastAPI Backend ↓ Document Processing Orchestrator ↓ Extraction / OCR ↓ Normalization ↓ Transaction Processing ↓ Rule Manager ↓ Validation & Reconciliation ↓ Structured Results ↓ Excel / CA-ready Output

The AI layer is intentionally not responsible for deterministic calculations.

Python handles things that should be predictable and reproducible, while AI/RAG is used where natural-language understanding and document interaction actually add value.

Why I'm building it:

I recently discussed the idea with a CA and got an important piece of feedback:

The goal shouldn't be to replace the CA's professional judgment — it should be to eliminate the repetitive work around it.

That changed the direction of the product.

I'm now refining DocuMind around workflow automation, accuracy, traceability, privacy, and useful outputs rather than trying to make AI “diagnose” financial information.

What's next:

I'm currently working on:

Improving the CA-focused workflow

Better document extraction

More robust validation

Source/page-level traceability

Better Excel outputs

Testing the workflow with real CAs

Expanding into additional financial-document workflows

Eventually building a more complete AI-powered document assistant

This project has been a great learning experience because I'm not just building features — I'm learning how to turn a real-world problem into a software architecture.

Tech Stack:

Frontend: React, Vite, Tailwind CSS Backend: Python, FastAPI Database: SQLite, SQLAlchemy Data Processing: pandas, openpyxl Documents: PyMuPDF, pypdf, Tesseract OCR, Tabula AI/RAG: Ollama, ChromaDB, Sentence Transformers Authentication: JWT Deployment: Local-first architecture, with cloud deployment planned for later

I'm currently open to freelance and full-time opportunities in:

Full-Stack Development · Backend Development · Python/FastAPI · React · AI Automation · Document Processing · SaaS Development

Building products that solve boring, expensive problems is what I want to do more of. 🚀
