Case 01 / Document intelligence
From 62% to 94% extraction accuracy
A fintech team had an LLM-powered document parser that passed QA in staging. In production, edge-case documents caused silent misclassifications that made it downstream before anyone noticed. (Silent failures are the worst kind — they're polite enough not to alert you while they're breaking things.) We built a behavioural eval suite against 800 real documents, redesigned the extraction prompt architecture with explicit fallback contracts, and shipped a monitoring harness that catches drift before users do.
