What I'm looking for

I'm looking to apply SQL, Python, Excel, and Power BI to build data-driven solutions, interactive dashboards, and machine learning analyses that create measurable business value.

I've built end-to-end data analyses across SQL, Python, Excel, and Power BI, including an MTN Nigeria churn investigation that identified ₦58M in lost revenue and ₦83M at risk. I also developed and evaluated churn prediction models, with Random Forest achieving 72.82% accuracy.

In freelance data and sales operations work, I created KPI dashboards that reduced manual reporting time by 30%, maintained over 99% CRM data accuracy, and redesigned Asana workflows to improve task completion efficiency by 20%.
