Ops teams processing invoices, applications, or compliance docs by hand
The problem
A team was re-typing hundreds of PDFs a month into their system. They needed extraction that survives real-world documents — scans, weird layouts, missing fields — with a human-review step for low-confidence rows.
What I built
- LLM extraction pipeline with schema-validated JSON output
- Per-field confidence scores and a review queue for low-confidence docs
- Batch upload with progress and webhooks
- Export to CSV / API / direct integration
- Audit log of every extraction and correction
The outcome
Cut document handling from minutes each to seconds, with humans only touching the edge cases.
