About Me

I've been fascinated by investing and Bitcoin since I was 16, and I've been actively involved ever since.

Today I study Economics & Finance at the Institute of Economic Studies, Charles University, and work as a Business & Data Analyst at Coinmate.io — I like turning messy data into clear decisions.

I enjoy staying close to the finance community, taking part in programmes like the Mercator Club and the Prague Finance Institute. Beyond that, I've been going to summer camp for over ten years — the last four as a camp leader — and I unwind with frisbee and volleyball.
