About
A data analyst with an educator's clarity and a founder's ownership.
I am Deborah Ajayi, the founder of Debbylytics. My work combines data analytics, business intelligence, and education: I clean messy data, design decision-ready dashboards, and explain insights in a way stakeholders can actually use.
My background in Mathematics and Integrated Science Education from Obafemi Awolowo University strengthened my quantitative reasoning, teaching ability, and structured problem-solving. Those skills now shape how I approach analytics: clear questions, careful cleaning, readable visuals, and practical recommendations.
I am actively building a public project portfolio across Power BI, Excel, SQL, business reporting, customer service analytics, sales performance, and project performance dashboards while growing a community for aspiring data analysts.
