Automated Financial Receipt OCR & AI Assistant System

Category: ai-automation | Role: AI Automation & Backend Engineer — Designed 5-workflow financial pipeline, configured structured vision parsers, and implemented notification and authentication integrations.

Project Overview

Alpha Finance is an automated financial management ecosystem architected across 5 independent n8n workflows. The platform handles end-to-end receipt digitization, transaction bookkeeping, and personal finance advisory. Inbound receipt images are processed via OpenAI GPT-4 Vision using a Structured Output Parser that deterministically extracts merchant details, dates, itemized costs, tax amounts, and totals into normalized JSON. A conversational financial assistant powered by GPT-4 with conversation memory answers budget queries, while companion workflows handle automated transaction categorization, email OTP authentication via Gmail API, and push notification alerts.
