About Me

Data Analyst with 5+ years of experience turning complex datasets into decisions that reduce losses, improve operations, and drive revenue — across energy & utilities, and supply chain.

At Kaduna State Power Supply Company, I led electricity billing analytics for 300+ Kaduna State Government facilities, managing consumption data across thousands of metered and estimated accounts, identifying billing discrepancies, and delivering management-level reports that directly influenced tariff decisions.

Before that, I spent 3 years at Eko Electricity Distribution Company conducting energy audits, energy theft detection, and optimising meter-reading strategy across Ikate zone, Lekki district in Lagos.

I hold an M.Sc. in Mathematics (University of Ibadan) and four professional certifications — IBM Data Analyst, Google Data Analytics, Advanced Google Data Analytics, and Power BI Developer of the Future with Microsoft Fabric — which supports a rigorous, quantitative approach to every data problem I solve.

My technical toolkit includes Power BI, SQL, Python, Excel, Tableau, and Microsoft Azure. I specialise in building reporting environments, data pipelines, and dashboards that give leadership clean, reliable visibility into business performance.
