Aishat Adebayo
Portfolio

I’m a data analyst with a strong foundation in data wrangling, exploratory analysis, and dashboard design. Leveraging tools like Excel (advanced formulas, pivot tables, and visualizations), SQL for querying relational databases, and BI tools such as Tableau and Power BI for building interactive, user-friendly reports. I enjoy exploring patterns, identifying trends, and presenting findings in a way that’s both accurate and accessible.
I believe data should not just inform, but inspire action—and I love being part of that process.
