ABOUT ME
Hello, and welcome to my data portfolio! I’m Doreen, a self-taught Data Analyst with an interest in using data to uncover insights, solve problems, and support better business decisions.
My work focuses on taking raw data and turning it into something useful, from cleaning and transforming datasets to analyzing trends, building reports, and creating dashboards that make information easier to understand.
I currently work extensively with Microsoft Excel, using PivotTables, formulas, and dashboards to explore and communicate insights. I’m also expanding my toolkit into Power BI, SQL, and Python as I continue to develop my data analytics skills.
The Projects section showcases my work and gives you a closer look at how I approach data, from the initial dataset through to analysis and presentation.
Feel free to explore.
