A North American FinTech startup needed an open-banking dashboard that aggregates accounts from 20+ banks, categorises 100k+ transactions per user, detects anomalies (unusual spend, potential fraud), and provides AI-generated monthly financial health summaries — all with bank-grade security and PCI DSS compliance.
FinTrack integrates with Plaid for bank-agnostic account aggregation. A Python ML pipeline auto-categorises transactions with 94% accuracy, detects spend anomalies, and generates plain-English weekly summaries. The React dashboard features D3.js-powered spending charts, net-worth timeline and investment portfolio view. A Node.js API layer with AES-256 encryption, OAuth 2.0 and PCI DSS Level 1 controls secures all financial data.
