I will review one synthetic or de-identified CSV sample (up to 20 rows) and up to three cleanup rules you provide. You will receive a one-page findings report, a cleaned example CSV, and an exceptions list explaining rejected rows. This is a scoped review and example, not a reusable script, production deployment, or ongoing support.

My portfolio sample is self-built with AI assistance; it is not paid client work. I use AI assistance in delivery and check the output against the agreed rules. Message me first with the column names, 5–20 safe sample rows, desired output, and the rules. Please do not send credentials or sensitive customer data in an initial message. Price and delivery start after we agree the sample, rules, and scope.
