Hello, I'm Jonah.
I'm a data analyst that is interested in understanding problems, uncovering patterns, and finding the story behind the numbers.

My approach to analysis revolves around identifying common or recurring problems, digging into the data, and figuring out why they are happening. I'm less interested in simply reporting what happened and more interested in understanding the story behind it — what changed, what might be causing it, and where the problem actually lies.
My toolkit includes Excel, SQL, Python, Power BI, and an unhealthy amount of curiosity. I enjoy the entire process of working with data — from cleaning the wonderfully chaotic stuff that people insist is "ready to analyse," to building dashboards and reports that make the final answer easier to understand.
I'm constantly learning, experimenting, and finding new ways to approach problems — while of course, occasionally discovering that the reason my analysis wasn't working was because I forgot one comma three hours ago.
Data can tell you what happened. I want to know why.
Selected Work
A collection of data projects where I explore problems, work through the data, and turn the results into understandable insights.

An end-to-end data analytics project analyzing child nutrition inequalities in Nigeria using WHO Global Health Observatory data. The analysis explores how wealth, educational attainment, and place of residence are associated with childhood nutrition outcomes.

An analysis of Nigerian Professional Football League data, exploring performance patterns, team statistics, and other insights from the league.
Coming Soon
Another data project is currently in progress. More details will be added soon.
Writing
My projects don't end when the dashboard is finished. I write about the process behind my analyses — the questions I started with, the problems I encountered, and what the data ultimately revealed.
