Sylwia in a few words
I turn complex data into clear, powerful insights that drive action!

I’ve helped companies save millions and work smarter by making their data work harder. Passionate about smart solutions and great UX, I deliver results that make a real difference.

Let’s team up and turn your data into your biggest advantage!
