About Me

Portrait of Yussuf Ahmed

My journey into data analysis began with a curiosity about how data can be used to tell stories and inform strategies. I have a strong foundation in SQL for data querying, Excel for data manipulation, and visualization tools like Tableau and Power BI to create impactful dashboards.

Over the past few months, I’ve completed multiple real-world projects, each focused on solving real business problems, backed by data-driven recommendations and dashboards.

Currently, I’m seeking an opportunity to grow as a data analyst, where I can contribute to data-driven decision-making while continuing to build my skills in a collaborative environment.

My goal is to leverage my analytical skills and business acumen to help organizations make informed decisions based on data. I thrive in dynamic environments where I can apply my technical expertise and creativity to solve complex problems.
