Data Analyst

I'm a data analyst with an MBA who ranked in the top 1% of a data storytelling cohort. That combination means I don't just run the numbers; I understand what they need to do for the business.

When I built a churn prediction model that hit 75% accuracy, I didn't stop at the notebook. I translated it into a Tableau dashboard that sales teams actually used to identify at-risk accounts. When I automated a revenue reconciliation system, I didn't just write Python scripts-I quantified the financial impact and handed finance teams actionable reports to recover lost revenue.

I work with SQL, Python, Power BI, and Tableau across healthcare analytics, supply chain optimization, and sales analysis. My projects span correlating air quality data with respiratory hospital cases in Lagos, tracking subsidy disbursement efficiency across Nigeria, and building automation pipelines that cut manual work by 75%.

What drives me? Taking complex datasets and making them clear enough that someone can take action. Every dashboard I build, every analysis I run, every insight I generate has one goal: move the needle. Check out my projects below to see the problems I've solved, the methods I used, and the outcomes I delivered.
