Product and operations analyst transforming data into dashboards, insights, and automated pipelines.
NigeriaWhat I'm looking for
I’m a Product and Operations Analyst who builds data products that teams can trust—automating ETL/ELT and creating analysis-ready datasets, dashboards, and KPI scorecards. I’ve investigated high-volume operational signals and customer journeys, turning them into actionable SOPs, FAQs, and clear improvement opportunities.
In my recent roles, I’ve reduced repeat escalations (25%) and cut manual reporting time (40%), while supporting data-quality improvements and faster reporting turnarounds. I’m also a Microsoft Certified Power BI Data Analyst and Google Analytics-certified, with hands-on experience delivering forecasting, retention/churn insights, and operational performance monitoring across multiple locations.
