About
I'm Sino — an aspiring data analyst based in Prague. This autumn I'm starting a Master's in Applied Data Analytics & AI at VŠE Praha (Faculty of Informatics and Statistics).
My focus is on the full analytics workflow: from writing complex SQL queries and cleaning messy datasets to building ML models and communicating findings clearly. I'm looking for internship opportunities at Prague-based data teams.
