Toluwani Bankole

I’m a data analyst who uses Excel, R, SQL, and Power BI to turn raw information into practical decisions. I’m especially focused on data quality—cleaning, transforming, and validating datasets so insights are reliable and actionable.

In my recent roles, I’ve improved data gathering and efficiency for real operational needs, including a 24% increase in gathered data on distressed houses and a 10% efficiency gain by filtering out non-matching records. At Expaat, I used RStudio for data cleaning, manipulation, visualization, and a bit of machine learning on a weather dataset, worked directly with stakeholders, and delivered the project 3 days before the deadline.

I also bring an educator’s mindset to analytics. I’ve trained 15 students on Excel, Power BI, R, and SQL, mentoring them with real-life datasets to help them become job-ready, and I’ve taught professionals across different sectors to apply data analytics in their work. My projects—customer sales analysis dashboards with DAX, accident/fatality hotspot investigation using Power Query and Power BI, and weather EDA/forecasting with regression and ggplot2—reflect the same drive to uncover meaningful patterns and communicate them clearly.
