About

Curious about numbers, driven by impact.

I'm Sewhenu Junaid, a data analyst based in Nigeria. My journey into data started with mathematics — I studied Applied and Pure Mathematics at the University of Ibadan, where I fell in love with the way numbers could describe patterns hidden in plain sight.

That fascination naturally pulled me toward analytics. I started teaching myself Excel, then SQL, then Power BI — building small projects, breaking them, and rebuilding them until the workflow made sense end-to-end. Each dataset felt like a puzzle: clean it, question it, visualize it, and let the story surface.

What drives me is the moment a dashboard or report shifts someone's thinking — when raw numbers turn into a decision. I care about the craft: clean data models, honest visualizations, and analyses that stand up to scrutiny. I'm ready to bring that curiosity and rigor to a team building things that matter.
