Why I’m Starting This Blog

Hi there — and welcome!

I’m Istvan Rozsa, a data enthusiast based in Prague (though I’m often sipping coffee somewhere between Vienna, Budapest, and Debrecen). After years of working on data warehouses, ETL pipelines, and BI solutions, I realized I wanted a space to share more than just dashboards.

This blog is where I’ll write about the technical stuff I build — and the human stuff I learn along the way. I’ll break down data concepts, share my own project experiments, explore how analytics impacts business decisions, and probably sneak in the occasional coffee shop review.

Whether you're a fellow data nerd, a curious learner, or just here for café tips, thanks for stopping by.
Let’s build, learn, and sip coffee together.
