I’m a curious and detail-oriented professional with a strong interest in using data to explore patterns, solve problems, and support better decisions.
With certificates in Google Advanced Data Analytics and several other courses, I've refined my skills in Excel, Tableau, Power BI, SQL and Python. I enjoy turning raw data into meaningful stories and continuously learning new tools and techniques along the way.
Thank you for stopping by—I’m always open to new challenges and collaborations that allow me to grow and contribute through data.
