I’m Fero. I work full-time, and in my free time I spend it on something I genuinely enjoy: data, analytics, and Power BI.
How I approach it
I don’t like guessing where I can measure instead. Before I build a report, I want to understand where the data comes from, how often it changes, and where it could be misleading. Only then does the visual design matter.
That’s exactly how the VIE/BTS Aviation Tracker came about — a project I built in my free time to systematically track how Vienna and Bratislava airports trade passengers between them. The full code and methodology are public.
What I enjoy
- Building data pipelines that run themselves and don’t need manual upkeep
- Dashboards someone actually opens again a week after publishing — not just on presentation day
- Explaining data to people who aren’t analysts, without dumbing it down
