I will clean, analyze and document your dataset in python and sql

You send me a messy export CSV, Excel or a database dump and I send back a dataset you can

actually trust, plus the analysis you asked for.

I have done this on real-shaped data: 1,458 import shipment records containing 20 documented defects,

including 1,765 ambiguous dates, 18 duplicate records and 22 conflicting tariff codes representing

MXN 1.2M of duty exposure. Every cleaning decision is logged with its evidence, so you can see what

changed, why, and what to undo if you disagree.

What you get:

- A cleaned dataset (CSV or Excel) plus a documented decision log

- Summary statistics and the charts that answer your question

- SQL cross-checks where the source allows them

- A written summary of what the data supports and what it does not

I will tell you when your data cannot answer your question. That is a feature: it is far cheaper than

a confident number that falls apart in the meeting.
