📊 The Analyst’s Toolkit I.
Kicking off my Analyst’s Toolkit series, I have to start with my first “best friend”: Tableau Public.
But before I tell you why I love it, I have to tell you how I found it.
My Catalyst for BI
My journey into Business Intelligence started with a challenges. Back when I was working at Intrum, our tool of choice was QlikSense. For about a year, I fought with it and trying to bend the data to my will, building complex calculations, and constantly feeling limited by the tool rather than empowered by it.
That frustration became my motivation. I knew there had to be other ways to visualize data, so I started exploring Tableau on my own time. That curiosity changed my career. Soon after, I joined Starschema, where I had the absolute luxury of working alongside some of the best data analysts in Hungary. Seeing what the pros could do with Tableau was a revelation.
More Than Just a Free Tool
If you think Tableau Public is just a “lite” version of the professional software, you’re missing the point. It is the most powerful career-building platform in the data world.
Steal with Pride (The Analyst’s Secret)
One of the best features of the platform is you can download any public workbook and see exactly how the world’s best developers structured their containers, built their calculated fields, and achieved that clean “SaaS” look.
A great place to start: search for Viz of the Day picks and download the ones that impress you. Reverse-engineer them. That’s how you level up faster than any course can teach you.
My Work in Action: The Nerazzurri Success
To show you what this looks like in practice, I stepped away from corporate KPIs and focused on a lifelong passion: Inter Milan.
Being a massive Nerazzurri fan, I wanted to showcase the club’s recent success through a professional lens. Applying the same executive-style clarity I use at Hyundai to the Beautiful Game. It’s one thing to say Inter is successful. It’s another to see the data prove it.
Learn from the Masters
I didn’t reach Senior level by guessing. If you want to level up, these three resources are non-negotiable:
The Takeaway: Just Do It
The biggest lesson I learned from my time at Starschema and my transition to international roles is this: you can only learn this by doing.
Just do it.
