Martin Dudumi, Excel expert and freelance data consultant
THE PERSON BEHIND THE WORKMartin DudumiExcel & data expert. Based in Tirana, working worldwide.
A REAL PERSON BEHIND EVERY PROJECT

Hi, I’m Martin.
I connect the dots.

I’m a freelance data consultant and Excel expert with more than 16 years of experience across engineering, data, and business. I build practical tools and solve reporting problems, drawing on operational analytics at Bankers Petroleum Albania and AI evaluation and human data management at micro1.

I hold a Master’s in Petroleum Engineering and am pursuing a PhD. My approach is practical: understand the system, question the assumptions, and build something useful.
