About
A short
introduction
I am a mechanical engineer with an MBA from IESE Business School, currently working in business management and strategy within the financial sector in Switzerland.
I am passionate about investing, macro finance, mining, and entrepreneurship — with a strong interest in building businesses at the intersection of technology and capital allocation.
Based in Zurich, I also enjoy hiking, sailing, and exploring new ideas across industries and disciplines.

Focus
Where I spend
my attention

Macro Finance
Reading the cycle. Currencies, rates, commodities, and how capital flows shape the real economy.

Mining
The physical layer beneath every modern supply chain. Resource scarcity, capex cycles, and operator quality.
04
Entrepreneurship
Building durable businesses at the seams between technology and capital — where neither side alone is enough.
