About Me
Hey, I’m Abdulrasaq Umar Yakubu but you can call me theabdool.
I’m a Data Analyst and Business Intelligence Developer who’s all about turning numbers into narratives that make sense.
I don’t just clean data and build dashboards, I dig deep to find what really matters. Whether it’s spotting trends, uncovering patterns, or helping teams make smarter decisions, I’m here to make data less intimidating and more impactful.
Tools like Power BI, Tableau, Excel, PostgreSQL, and Python? That’s my daily toolkit.
But what sets me apart is how I use them to tell clear stories, spark conversations, and drive results that matter to real people.
Let’s just say: I don’t build charts for decoration; I build them to make a difference.
