About this Gig

Is your Excel messy or your database slow? I will fix it FAST.


I clean dirty Excel/CSV AND write SQL queries that actually work. Perfect if you need 2-in-1


WHAT I DO FOR EXCEL:

- Remove duplicates, trim extra spaces, fix formatting

- Fix and standardize messy locations - provinces, states, cities (e.g. W.Cape -> Western Cape, CA -> California)

- Standardize emails, phone numbers, names

- Clean 100 to 1000+ rows using Excel and Python (pandas)


WHAT I DO FOR SQL AND PYTHON:

- Write 1-3 custom SQL queries (SELECT, JOIN, WHERE, GROUP BY)

- Optimize slow queries and fix errors

- Clean data directly inside MySQL or using Python

- Create before and after reports in Excel


WHY ME?

I built a case study on the Madlanga Commission - tracking R5B unspent by Land Reform, R13-14B by UIF, officials on full pay for 7 years, and ballistics backlogs. I mapped it with Risk Analysis (Single Point of Failure, Moral Hazard) and designed 3 trackers: Suspension Tracker in MySQL, Unspent Funds vs Delivery in Python, and Vetting Gap analysis.


You'll get Clean Excel/CSV file ready to use + working SQL queries + explanation + revisions.
