About Me

I’m a data analyst who turns messy data into clear, actionable insights. I work end-to-end—from collecting and cleaning data with SQL and Python, to building intuitive dashboards in Power BI and Excel that tell a story and drive decisions. I enjoy partnering with stakeholders, defining the right metrics, and validating results so recommendations are trustworthy and practical.

I’m currently exploring how AI can elevate analytics—using LLMs to speed up data exploration, automate documentation, and prototype predictive workflows that plug into my SQL/Python stack. When I’m not working, I like solving logic puzzles, cycling, and learning through data-driven side projects. I’m always open to new challenges and collaborations—let’s build something insightful.
