Olufikayomi Jolaoso

I’m a results-driven Data Analyst with hands-on experience in data collection, data cleaning, data visualization, and business intelligence reporting. I’m proficient in SQL, Microsoft Excel (Power Query, Pivot Tables, VBA/Macros), Power BI, and Tableau, and I focus on transforming raw data into actionable insights for decision-making.

In my recent role, I spearheaded end-to-end data entry operations for logistics workflows, processing 500+ records weekly into a TMS with a 99.5% data accuracy rate, driving a 15% reduction in data-related errors. I also redesigned the data entry workflow and validation checks to cut processing time by 40%, and I audit-reconciled data across invoices and shipment logs to improve reporting reliability—supported by weekly KPI reporting and structured digital filing. Through projects like interactive Power BI dashboards and Excel-based RFM/customer segmentation analyses, I continue to deliver clear, data-driven storytelling to both technical and non-technical stakeholders.
