Hey there!
I'm Ervisa, a Data Analyst at one of the largest fleet management companies in Europe. With an MSc in Econometrics and Operational Finance and experience across Real Estate, Tech (Ride-Hailing), and Fleet Management, I’ve developed a deep understanding of data and how to turn it into insights.
One thing I’ve learned? The best way to master something is by actually doing it. Just start, and before you know it, you’ll have learned more than you ever expected, without even realizing it. And that’s the fun part.
I hope you enjoy my course, have fun and just go for it!
