About this gig

Turn messy spreadsheets into a clean, automated dashboard that updates itself.

Hi, I'm Mert a business analyst who builds forecasting and reporting systems for real commercial operations. I'll turn your raw data into a clear, interactive Excel dashboard that actually gets used, not just one that looks nice.

What you get:

  • Interactive dashboards with KPIs, charts, and filters
  • Automation so your numbers update the moment you paste new data no manual rework
  • A clean, professional layout your team or clients can read at a glance

I work with sales data, inventory, finance, and marketing metrics. If you can export it to Excel or CSV, I can turn it into something you'll open every day.

Why me: I build demand-forecasting and reporting infrastructure on large-scale commercial data, with 150+ custom measures across live dashboards. You get that same rigor on your project.

Message me before ordering with a sample of your data so I can confirm scope and recommend the right package.

FAQ

  • What file formats do you accept? Excel (.xlsx), CSV, or Google Sheets exports. If it's tabular, I can use it.
  • Will the dashboard update automatically? Yes Standard and Premium are built so you just paste new data

Background: demand & business analyst for one of Turkey's largest FMCG supply chains, plus a mechanical engineering degree — so accuracy always comes first. Tools: Excel, Power BI, SQL, Python. Tell me your data problem and I'll show you how I'd solve it.
