I developed a multi-tenant financial platform with AI OCR, and here's the architecture that makes it work
Been building YourFinanceWORKS for 2 years - a financial automation platform that processes receipts, invoices, and bank statements using AI. Here's the tech stack that handles it all:
Backend:
- FastAPI + PostgreSQL (database-per-tenant for security)
- Kafka for background processing
- AI integration with OpenAI, Ollama, and custom OCR models
Frontend:
- React + TypeScript + Vite
- Tailwind + ShadCN UI components
- Real-time dashboards with interactive charts
Key Features We Built:
🔍 AI-powered OCR - 95%+ accuracy on receipts and invoices
🧠MCP integration - Model Context Protocol for secure AI data access
🏢 Multi-tenant architecture - Complete tenant isolation
đź“Š Business intelligence - Natural language queries to financial data
🛡️ Fraud detection - AI auditor that flags phantom vendors, duplicate billing
Cool Technical Challenges:
- Database-per-tenant scaling with connection pooling
- Background OCR processing with worker queues
- Real-time risk scoring on every transaction
- Plugin system for extensibility
The code is open-source (AGPL) with commercial features available.
