I audit data, build SQL pipelines, and deliver accurate Power BI KPI dashboards.
NigeriaWhat I'm looking for
I've built SQL and Power BI analytics projects spanning Nigerian fuel pricing, online retail, HR attrition, and telecom churn. My dashboards turn validated source data into actionable KPIs, including identifying that 1% of retail customers generated over 60% of $8.91M revenue and that month-to-month telecom contracts drove 43% churn.
Before moving into data analytics, I enforced quality-control standards as a Site Engineer at StructDevNig Ltd on World Bank and university construction projects. I bring the same discipline to reconciling reported figures, checking joins, filters, and aggregations, documenting workflows, and catching inconsistencies before they become costly decisions.
