About this gig

Your sales data is scattered across spreadsheets, exports and store reports, and nobody trusts the numbers.


I turn it into one clear Power BI dashboard your team actually uses. I work as a BI analyst on a sell-out project for a global fragrance and beauty group, auditing and consolidating point-of-sale data from hundreds of stores. I know retail data: duplicated SKUs, store names spelled five ways, missing weeks. What you get:


Clean data model (star schema) built from Excel, CSV, SQL or Google Sheets, KPIs that matter: sales, units, average ticket, growth, top products and stores Filters by period, region, store, brand or category DAX measures documented so you can maintain them .pbix file + short walkthrough video Not sure which package fits?


Send me a sample of your data and I will tell you before you order.

I turn messy, inconsistent business data into reports you can actually trust. I'm a data analyst working with Python, SQL and Power BI, specialized in cleaning and standardizing sales data from real-world sources — spreadsheets, PDFs, XML and ERP exports. I've built automated pipelines and audit routines covering 60+ retail clients, catching reporting errors worth hundreds of thousands of dollars. Send me a sample file and I'll tell you honestly what can be automated and what can't. Clear communication, documented rules, delivery on time.
