About this service

Summary

I create clean, reliable dashboards in Power BI or Excel that transform raw data into decision-ready visuals. With 15+ years of experience, I specialize in turning messy spreadsheets into clear, actionable insights. I’m responsive, detail-oriented, and deliver work you can rely on.

My dashboards have helped clients in telecom, retail, and operations save time, reduce reporting errors, and easily track performance trends. I can also support data cleanup or add automation with SQL, Power Query, or VBA to keep reporting accurate and refresh-ready.

FAQs

What tools do you work in?
I primarily use Power BI, Excel, SQL, and Power Query. I can also handle Excel VBA or CSV-based workflows if needed.
Can you update my existing spreadsheet or dashboard?
Absolutely. I can either improve what you have or rebuild it from scratch for better clarity and function
Can you work with sensitive or private data?
Yes — I’ve worked with confidential telecom, finance, and HR datasets. I’m happy to sign an NDA if required.
Can you make the dashboard update automatically?
Yes: I can connect your dashboard to data sources and configure Power Query, SQL, or automation so it refreshes with new data instead of needing manual updates.
