Nigeria

Message

At AfyaCare Nigeria Limited (R-Jolad Hospital), I built and maintain a PostgreSQL healthcare warehouse fed by incremental ETL pipelines across eight branches. Power BI serves as its reporting layer.

I designed a Visit_ID inheritance system to connect clinical records to a single encounter, and cleaned heavily duplicated extracts before validating fact tables against their sources. I also developed a Python audit tool that reports data accuracy and automates alerts to data stewards.

Earlier, I analyzed operational and sales data at Mizar Eridanus Limited to support LPG pricing, stock, and demand decisions. Independently, I built an ESG analytics pipeline and interactive dashboard from a public oil spill dataset, examining incidents and operator response timelines across the Niger Delta.
