TIJANI OLAYIWOLA

I’m a Data Analyst and Data Scientist with 5+ years of professional experience across analytical consulting, commercial operations, and enterprise data leadership. I specialize in transforming fragmented datasets into structured intelligence through exploratory analysis, predictive modelling, and dashboard development.

In my current role as a Data Analytics Consultant (AMDARI, London), I lead analytical delivery across client datasets and build insight frameworks that support strategic decisions. I’ve designed and deployed Power BI and Looker dashboards tracking 10+ operational KPIs, and I’ve re-engineered SQL-driven data transformation workflows to improve dataset reliability and speed up preparation for reporting and modelling.

Previously at KWE4 Africa (Lagos), I engineered predictive analytics models using regression and time-series techniques, improving lead conversion forecasting accuracy by 15% and supporting a 10% reduction in customer churn through targeted campaign optimization. I also built and deployed 10+ Power BI dashboards consolidating CRM, sales, and marketing datasets, and I integrated multi-source data for more unified analytical modelling.

Earlier, as Chief Data Officer at DATAAD Petrochemicals (Lagos), I directed enterprise data strategy and operational analytics while managing a $200K operational budget, consistently achieving 5% cost savings via structured financial monitoring. I led a 20+ person team, architected operational data workflows that reduced processing time by 20%, and improved customer satisfaction by 12% while reducing complaint volumes by 10% through performance monitoring systems—always pairing data storytelling with actionable recommendations.
