Mftahi PropTech platform empowers Saudi KSA residents to divide annual rent into flexible monthly payments. Built with a high-performance Flutter frontend (Dart) and a robust Node.js (TypeScript) backend hosted on secure AWS cloud, it uses a PostgreSQL database. It seamlessly integrates Saudi digital infrastructure: identity verification via Nafath, credit risk screening via SIMAH, official rent contract sync via Ejar API, automated secure monthly split-billing processing through Mada, and ZATCA Phase 2 compliant e-invoicing.
