Hi there 👋 I'm Augustinas

I'm a Data Analyst with a background in IT Operations, working mainly with SQL and Python (plus Tableau/Power BI when visuals help). I like turning messy data into clear insights and building practical reporting that supports better decisions.

Outside of work I’m into running, chess, and spending time in nature.
