Integrated an embedded AI Assistant for instant natural language querying over system data, financial reporting, and operational guidelines. Implemented role-based access control (RBAC), multi-tenant data isolation, real-time audit logging, and automated repayment tracking. Built comprehensive administrative tools for staff management, borrower onboarding, and interactive business performance dashboards.
