I will clean, reconcile, and audit your messy sql or CSV data
About this Gig
Your data has duplicates, missing values, type mismatches, or two systems that don't agree on the same numbers. I fix that.
I spent over four years reconciling healthcare data across systems at the CDC, where a single wrong number can mean a wrong public health call. I built an automated tool that runs 11 data quality checks (missing values, duplicates, type mismatches, outliers, string inconsistencies, date errors) and hands back a ranked, plain-English report instead of a wall of red cells.
What you get:
- A cleaned dataset (CSV, Excel, or SQL table) with every fix documented
- A short report: what was wrong, what I changed, what still needs your judgment call
- If two sources disagree, a reconciliation summary showing where and by how much
I don't guess on ambiguous fixes. If a value could mean two different things, I flag it and ask rather than silently picking one.
Requirements from buyer: the raw file(s), a short note on what "correct" looks like (a source of truth column, a business rule, or just "flag anything weird").
FAQ
Can you work with SQL Server / Postgres / Snowflake directly, not just files?
Yes, send connection details or a read-only export.
What if my data has sensitive info?
Anonymize or mask it before sending, or we scope the job to a schema/sample first.
Can you build a recurring check, not just a one-time clean?
Yes, that's the Premium tier or a custom quote for ongoing work.
