Design a secure, highly-available mortgage agent platform that facilitates lead management, document collection, and integration with third-party financial services. The system must handle high-volume document uploads (PDFs/Images), ensure strict PII data protection (GLBA compliance), and manage asynchronous workflows like credit report fetching and loan status updates. Focus on document lifecycle management, external API integration reliability, and a robust security architecture for financial data.

Mortgage Application & Document Management System

Design a high-security, workflow-driven application for mortgage agents to manage loan applications. The system must support document uploads (bank statements, tax returns), status tracking across a multi-stage lifecycle, and agent-specific dashboards. Key constraints include handling highly sensitive PII, ensuring strict auditability of status changes, and maintaining system responsiveness under high-volume document processing. Address how you would scale to 10,000 agents and ensure 99.9% availability while complying with financial data regulations.
