Document Compliance Pipeline

An automated document processing pipeline built for regulated environments where extraction accuracy and compliance validation are non-negotiable. The system ingests documents in bulk, extracts structured data via OCR and GPT-4, validates every field against configurable compliance rulesets, and routes approved documents downstream with a full audit trail.

The Challenge

Businesses operating under strict regulatory requirements were manually processing hundreds of documents per week. Each document required field-by-field extraction, validation against compliance rules (expiration dates, required signatures, format constraints, cross-field dependencies), and routing to the correct system. A single missed field or expired certificate could trigger fines or failed audits. The manual process was slow, inconsistent across reviewers, and left no reliable audit trail.

Our Solution

Built an automated pipeline using Tesseract OCR for text extraction, GPT-4 for intelligent field parsing and context-aware validation, and a configurable compliance rules engine stored in PostgreSQL. Each document passes through extraction, field-level validation, cross-field dependency checks, and a final compliance gate before being routed. Every step is logged with timestamps, confidence scores, and the specific rule that passed or failed. Documents that fail any rule are flagged for human review with the exact failure reason highlighted.

Key Features

Confidence scoring per extracted field
Automatic routing for approved documents
Human review queue with failure reason highlighting
Full audit log with timestamps and rule traceability
FastAPI endpoints for integration with existing systems

Results

  • 85% reduction in document processing time
  • 99.2% extraction accuracy on structured fields
  • Zero compliance violations since deployment
  • Full audit trail for every document, field, and decision
  • Reduced reviewer workload to edge cases only
