01
Intake & classification
Bank statements, tax schedules, and credit reports are fingerprinted, virus-scanned, and routed to the correct extraction agent before any human review.
FLAGSHIP ARCHITECTURE
Global Institutional Lending
Fintech Automated Underwriting & Intake Engine
Replaced manual underwriting choke points with an autonomous parsing infrastructure capable of cross-referencing multi-tiered business tax schedules, bank statements, and credit bureau reports under strict compliance mandates.

The Problem
Where the existing system broke down.
A four-hour manual loan document review bottleneck delayed every application, created inconsistent extraction quality across reviewers, and exposed the lender to avoidable compliance risk during peak intake periods.
What changed after delivery
- Every loan document reviewed against the same policy version.
- Audit-ready evidence trail for AML and credit decisions.
- Reviewer capacity redirected to exceptions instead of data entry.
The Architecture
A system designed for production pressure.
A deterministic multi-agent LangGraph workflow orchestrates document classification, OCR extraction, cross-document reconciliation, and policy validation. Every agent step is checkpointed to Postgres, sensitive documents stay inside a zero-retention private cloud boundary, and approved outcomes sync bi-directionally with Salesforce and the core ERP.
02
Hybrid RAG extraction
Pinecone hybrid retrieval grounds each extraction against lending policy, historical decisions, and AML controls with citation-level traceability.
03
Human-in-the-loop controls
Low-confidence fields escalate to a reviewer queue with the exact source page highlighted, while every override is written to the audit log.
04
ERP and CRM sync
Bi-directional webhooks push approved deals into Salesforce and the servicing ERP with idempotent retries and replay-safe event IDs.
