What I'm looking for

I’m looking for a role where I can use Power BI, SQL, and Excel to turn complex data into dashboards, KPI monitoring, and stakeholder-ready reports—supporting operational efficiency, strategic decisions, and, where relevant, sportsbook analytics.

I am a Data Analyst with two years of experience transforming complex datasets into meaningful insights that support operational and strategic decision-making. In my previous role at the Joint Admissions and Matriculation Board (JAMB), I analyzed candidate records, developed interactive Power BI dashboards, monitored KPI performance indicators, and produced data-driven reports for nationwide examination planning and admissions management.

I also strengthen my analytics expertise through independent football sportsbook analysis, where I regularly evaluate team and player performance, betting markets, expected goals (xG), corner statistics, odds movements, and historical trends to identify patterns and make evidence-based predictions. I’m proficient in Microsoft Excel, Power BI, SQL, and Python, and I enjoy using data to solve business problems, improve operational efficiency, and support organizational growth.
