Data Analyst · Berlin

Cascione

I spent over a decade using data to run operations across four continents. Now I build the analyses I always wished I had — with SQL, Python, and Tableau.

A different kind of
data analyst

“I know what decisions look like when the data isn’t good enough — because I’ve had to make them.”

My career started in international tourism and hospitality, where I led multi-market operations for a travel company active across Latin America, Africa, and Europe. I designed KPI frameworks, drove cost reduction, and built processes that scaled across borders.

What I kept running into was a gap: the data existed, but the analyses didn’t. I was the person who needed the insight — who had to decide whether to restructure a supply chain or double down on a route — and I learned exactly what questions data needs to answer to actually be useful.

After nine years based in Berlin, I made a deliberate move into data analytics. I work in SQL (PostgreSQL), Python (pandas, matplotlib, seaborn), and Tableau — and I bring an unusual angle: the perspective of the stakeholder, not just the analyst.
