About This Project
MMG is a multi-corridor FX and remittance back-office I architected and shipped solo for a UAE money-exchange client in about two months. It runs 14 live currency corridors, 98 REST endpoints, 18 PostgreSQL tables, and a 35-permission RBAC across 3 roles on TypeScript, Express, and TypeORM with a TanStack Start and React 19 frontend.
The core is a pluggable 7-engine FX calculation factory (direct, CFA-zone intermediated, USDT auto-detection, percentage, reverse-flow, mixed) that reproduces the client's 70-column Excel profit sheet to 0.01 AED, verified by a row-by-row parity harness. An E2E harness reached 125/125 pass before delivery.
