About

I'm a data analyst with a foundation in statistics, and a habit of asking "so what does this actually mean?" of every dataset I touch.

Across the HNG14 internship I worked through the full analytics stack — cleaning and modelling data in PostgreSQL, designing star-schema data warehouses, and building dashboards in Power BI and Looker Studio. I led one project team to a 4th-place finish out of 26, and analysed datasets ranging from a national budget to 15.78 million tweets.

I'm currently doing my NYSC in Lagos and looking for a place of primary assignment at a tech-driven company where I can keep growing toward data science. I learn deliberately, document my work carefully, and care about getting the details right.
