Nigeria

Message

At Interswitch Nigeria Ltd., I built production PostgreSQL ETL pipelines over settlement, merchant, and transaction data, helping cut settlement lag by 40% across 1M+ transactions worth over ₦1T.

I designed a duplicate transaction detection framework and transaction quality monitoring system that improved data accuracy by 30%. I also built Power BI dashboards for settlement intelligence, risk profiling, and reconciliation status, replacing a roughly two-minute lookup delay with near real-time visibility.

Earlier, as a Data Analyst Intern at ALDON Golden Global Ltd., I analyzed transaction datasets and developed operational progress-tracking dashboards. I also worked as a Software Engineering Intern at Datamellon Ltd. and built projects in machine learning, credit risk, exploratory data analysis, and Tableau.
