I turn raw data into clear Excel dashboards and actionable business insights.
NigeriaWhat I'm looking for
I've cleaned, transformed, and analyzed real-world datasets at Petra ICT Hub, using Microsoft Excel to turn raw information into clear reports and dashboards.
I build Pivot Tables, Pivot Charts, KPI reports, and interactive dashboards that highlight sales, product, and regional performance. I also use Excel formulas, data validation, Power Query, and basic Power Pivot to improve data accuracy and support decision-making.
In projects such as a Sales Performance Dashboard and Netflix Movies & TV Shows Analysis, I've standardized data, removed duplicates, developed KPI cards, and communicated findings through visual reports.
I'm also building my SQL skills with PostgreSQL, pgAdmin, Visual Studio Code, Git, and GitHub. I bring analytical thinking, attention to detail, clear communication, and a practical approach to data work.
