About
I study Applied Informatics at VŠE in Prague and work as a BI Analyst Intern on the Finance team at JetBrains.
Most of my work there is analytics engineering: building dbt models on production financial data, rewriting legacy SQL into cleaner models, and moving reports from Power BI to Tableau. Before that, I spent eight months at Euler Technologies, a small startup, building data-driven Python applications for clients.
I'd like to move further toward data engineering: ingestion, orchestration and pipelines. That's what most of my side projects are about right now.
Outside of work I climb, run, play volleyball and do cold plunges.
