About Gulum

I’m a data enthusiast with a background in Industrial Engineering and a Master’s in Information Systems. I specialize in data cleaning, Excel/Google Sheets automation, and SQL-based insights.
My strength lies in clear communication and turning messy data into clear, actionable formats. If you’re a startup or small company in need of clean dashboards, simple automation, or just a reliable hand for your reporting, I’d love to help.
