I clean, merge and reshape your data so it is ready for analysis, reporting or import into another system, with a repeatable script you can run again next month.

What you get

• One clean table from several messy files: CSV, Excel, exports from CRM, ad platforms, e-commerce or accounting tools

• Duplicates removed, formats fixed (dates, numbers, currencies, phone numbers, text case), categories standardized

• Validation checks and a short data quality report: what was wrong, what was changed, what needs your decision

• SQL queries or Python (pandas) scripts that reproduce the whole process, with comments

• Output in the format you need: Excel, CSV, Google Sheets or a database table

Also available: SQL data models and views for reporting, scheduled refresh scripts, and transformation logic for Tableau or Power BI.

How it works: send me a sample of the data and describe the target structure. I confirm the scope and the rules, deliver the cleaned data and the script within 2 to 4 days, and include one round of revisions.

Background: 3 years as a Data Analyst in iGaming, e-commerce and digital marketing, working daily with SQL (PostgreSQL, MySQL, Snowflake, SQL Server) and Python. Intro rate for first projects on Contra.
