I turn complex data into decisions. From cleaning million-record datasets to building BI dashboards and training ML models. I work across the full data pipeline to help businesses act on what the numbers are actually saying.

I'm a data scientist based in Lagos, Nigeria, with a mathematics background and a focus on applying data science to real, tangible problems.

I work across the full stack of data: cleaning and wrangling with Python and SQL, building dashboards in Power BI and Tableau, and building predictive models using Scikit-Learn and TensorFlow.

I've processed a census dataset of over 1 million records to surface policy-relevant insights, trained the next generation of data analysts at 5th Factor Academy, and delivered freelance BI and analytics solutions since 2023.
