What I'm looking for

I'm open to remote, hybrid, on-site, and relocation roles, and I'm available immediately.

At TechTutorsng, I cleaned and transformed datasets of up to 1,001 rows using SQL, Excel, and Python to improve reporting accuracy. I also built four interactive Power BI dashboards tracking 16 KPIs for stakeholder decisions.

I presented findings through visualizations and written reports, and taught digital marketing fundamentals to learners.

In my self-directed projects, I’ve analyzed coffee sales, customer churn, layoffs, and ultramarathon results. My work has included identifying that low-value customers had the highest churn and recommending re-engagement offers.

I use Excel, SQL, Power BI, and Python to explore data and communicate findings. I’m based in Nigeria, available immediately, and open to remote, hybrid, on-site, and relocation roles.
