I will clean your messy data and deliver a script that proves every change

About this Gig

Send me the spreadsheet nobody wants to open. I clean it by writing code, not by hand-editing cells, so every change is recorded and repeatable.


What that looks like: duplicates resolved with stated rules, dates and phone numbers in one format, categories reconciled, blanks resolved by rules we agree on, sources merged on real keys. The script that did the work ships with your order. Run it yourself and you get the same result.


Every delivery includes a validation report: row counts in and out, what was removed and why, uniqueness and range checks on the columns that matter.


Background: through Mercor, I'm a paid evaluator of data-engineering work built by AI coding agents, graded against executable checks. Before that, fifteen years of software engineering for clients including Mayo Clinic, JP Morgan Chase, and eSimplicity, where I built data platform tooling on a federal health contract.


US-based in Dallas. Files stay confidential and are deleted after delivery on request.
