Six-week embed with a regulated lender's compliance team. Built a reviewer-assist tool that surfaced flagged clauses with explanations the officers could accept, reject, or annotate. Officer review throughput rose 3.2x with no detected accuracy regression.

That is how the work earns trust—not with a louder claim, but with a clearer surface and receipts that match the field.
