About

I'm a data analyst with over four years of experience turning numbers into stories and insights that drive real impact. With a strong command of SQL, Python, R, Tableau, and Power BI. Having worked across industries like healthcare and telecom, I have experience handling complex datasets, optimizing processes, and building interactive dashboards that make data easy to understand. Whether it's automating reports, predicting trends, or solving tough analytical challenges, I thrive on making data work smarter. Passionate about continuous learning and problem-solving, I believe that behind every dataset is a story waiting to be told and I am always eager to uncover it.
