Multi-Agent Mortgage Underwriting System

Agentic AI portfolio demo by Chantell Harris-Headley. This interactive demonstration shows how a Supervisor coordinates specialized Credit, Income, Asset, Collateral, Critic, and Decision agents across a structured underwriting workflow.

What This Demonstrates

Supervisor Orchestration

Sequential routing and shared workflow state across multiple specialist agents.

Deterministic Calculations

DTI and LTV are calculated outside the language model for reproducibility and auditability.

Critic Review

A dedicated Critic layer reviews specialist outputs, flags risk, and determines escalation needs.

Human-in-the-Loop

Borderline and high-risk cases are explicitly marked for human review rather than fully automated disposition.

Privacy-Oriented Controls

The source project demonstrated PII masking before data is provided to an LLM.

RAG Policy Retrieval

The original project used ChromaDB-based retrieval for mortgage policy context.
