I build AI data pipelines you can actually trust.
Most extraction pipelines look fine in demos and quietly drift in production. I build the reliability layer on top: labeled eval sets, accuracy reports, confidence scoring, audit logs, and PII redaction — so you know exactly what your pipeline is doing, and you can prove it to anyone who asks.
