About Me

I’m a Data Analyst with a passion for transforming raw data into actionable insights that drive smarter decisions. With experience in software development, and customer support, I bring a unique blend of technical and analytical background with a passion for storytelling tied to business outcomes.

My main focus is helping businesses understand their data by uncovering trends, improving processes, and creating reports and visualizations that tell a clear story. I use tools such as SQL, Python (Pandas, NumPy), Excel, and Tableau to analyze, clean, and visualize data—turning complex information into easy-to-understand insights.

On this website, you’ll find a collection of my projects that showcase my skills in data analysis and storytelling with data.
