Adeniyi Ayeni | Data Analyst Portfolio

About

I am a Data Analyst with hands-on experience transforming raw data into actionable insights that support business decisions. I have worked on projects involving e-commerce performance analysis, customer behavior, and operational efficiency, where I used tools like Excel, Power BI, and SQL to clean, analyze, and visualize data for meaningful storytelling.

Currently, I am building more advanced analytics projects focused on business intelligence dashboards, performance tracking systems, and data-driven decision-makingmodels. I am also strengthening my skills in SQL optimization, Power BI DAX, and data modeling to handle more complex business problems and larger datasets.

I am continuously improving my ability to think like a business analyst—moving beyond just reporting data to identifying trends, uncovering opportunities, and recommending strategic actions that drive growth and efficiency.
