Project details
I clean messy datasets in Python so you get files you can actually work with. That means handling missing values, standardizing inconsistent formats and dates, removing duplicates, and fixing the structural problems that quietly break formulas, imports, and reports.
The work runs as a script using pandas and NumPy rather than by hand, so the same logic applies to every row and the whole process can be re-run when new data arrives. That matters most on files too large or too irregular for Excel to handle cleanly.
You get the cleaned dataset in the format you need, a short audit note explaining what was changed and why, and the script itself if you want to run it again yourself.

Job Success
Alexandria, Egypt - 1:14 am local time
Top Rated on Upwork with 30+ completed projects and a 100% Job Success Score. Most of my work falls into four areas.
DATA CLEANING AND ETL
Data that arrives duplicated, half-formatted, or spread across a dozen files becomes one validated dataset. Python (pandas, NumPy), SQL, Excel, and Google Sheets. Recent examples include a 20,000 SKU Shopify catalog build and a multi-carrier commission reconciliation system.
DATA ANALYSIS AND REPORTING
Exploratory analysis, statistical work, and business metrics, delivered as Power BI dashboards, Excel models, or written findings. I tell you what the numbers mean and what I would do about them.
DATA EXTRACTION AND DOCUMENT PROCESSING
Structured data pulled out of PDFs, scanned documents, and APIs using Python. This includes OCR work on non-English source material and automated collection where the data is not available as a clean export.
AI AND WORKFLOW AUTOMATION
LLM-powered scripts and agents (Claude API, GPT, MCP integrations) that run the repetitive parts of a data workflow: parsing documents, generating reports, calling APIs, and moving results where they need to go.
HOW I WORK
I start by asking what decision the data needs to support, because that usually changes the approach. You get a scope and a timeline before I start, updates while I build, and documentation someone else on your team can follow afterward.
