Midas Ledger is a next-generation personal and small-business finance app that automatically captures, categorizes, and aggregates every expense in one unified ledger. By leveraging state-of-the-art AI for receipt OCR, transaction parsing, and intelligent categorization, it frees users from manual data entry and delivers real-time insights into spending habits. Under the hood, Midas Ledger combines a React Native mobile front end, a Node.js/Express API layer, Python-based machine-learning microservices, and a PostgreSQL data store—deployed on AWS with secure, event-driven architecture.

Introduction

Managing expenses can be tedious. Receipts pile up, spreadsheets get outdated, and reconciling bank statements is a chore. Midas Ledger addresses this by:

Automatically capturing every expense—whether you pay by card, cash, or digital wallet.
Applying AI to extract key details (merchant, date, amount, category) from photos or PDF e-receipts.
Aggregating all transactions in a single, searchable, and shareable ledger.

Key Features

1. AI-Driven Receipt OCR

Snap or upload any receipt image or PDF.
On-device pre-processing corrects skew and lighting.
A Python/TensorFlow model performs OCR and extracts structured data (merchant, date, total) with >95% accuracy.

2. Real-Time Transaction Sync

Connect bank and card accounts via secure Open Banking APIs (Plaid/TrueLayer).
Ingest incoming transactions and match them to existing receipts or create new entries.

3. Intelligent Categorization

A microservice analyzes transaction descriptions and receipt line items.
Customizable category rules allow users to override or train the model over time.

4. Unified Ledger & Reporting

All expenses flow into a single PostgreSQL-backed ledger.
Generate custom reports (monthly spend by category, vendor trends).
Export to CSV, QuickBooks, or Xero via built-in integrations.

Technical Architecture

Front End

Mobile (iOS & Android): React Native with TypeScript.
Web Dashboard: React + Redux for user settings, analytics, and report exports.

Back End

API Layer: Node.js with Express, JSON Web Tokens (JWT) for auth.
AI Microservices: Python Flask services with TensorFlow and Tesseract OCR, containerized via Docker and orchestrated with Kubernetes.
Data Store: PostgreSQL for transactional data; Elasticsearch for fast search over receipts and descriptions.
Message Queue: RabbitMQ for decoupling ingestion, OCR, and categorization tasks.

Infrastructure & DevOps

Cloud Provider: AWS (EKS for Kubernetes, RDS for PostgreSQL, S3 for receipt storage).
CI/CD: GitHub Actions pipelines with automated testing, linting, and Docker image builds.
Monitoring & Logging: Prometheus + Grafana for metrics; ELK stack (Elasticsearch, Logstash, Kibana) for centralized logs.

Benefits

Zero Manual Entry: Automatic capture and AI parsing eliminate spreadsheets.
Accurate Insights: Real-time categorization reveals spending patterns as they happen.
Scalable & Secure: Cloud-native, containerized services ensure reliability and data privacy.
Extensible Integrations: Open API allows third-party integrations (accounting platforms, bill-pay services).
