About Me

I'm an emerging data professional based in Abuja, Nigeria, with a First-Class B.Sc. in Economics and an M.Sc. in International Economics.

Through hands-on projects, I use Excel, SQL and Power BI for data cleaning, reporting and business analysis — preparing datasets, summarizing performance and presenting findings clearly.

My work history in business operations, customer information management, administrative documentation and records management gives me practical experience handling real business information accurately.

I'm interested in helping organizations improve data accuracy, organize their business information and make better-informed decisions.
