OLUFUNMILAYO OLAWOYIN

I’m a Data Analyst with a Physics background and hands-on experience applying Excel, R, SQL, and Python to real-world problems in sales analytics, public health, and academic performance.

I focus on the full analytics workflow: cleaning and validating messy data, exploring patterns with correlation and regression, and building dashboard-ready outputs that stakeholders can actually use.

In my projects, I’ve built an interactive Shiny dashboard for movie analytics, created formula-driven Excel trackers for retail profit, and developed an Excel dashboard to optimize supermarket sales by day, payment method, and customer age group.

I’m also careful with model integrity—I identified data leakage risks in predictive work and rebuilt the analysis using independent predictors—while translating findings into clear requirements and actionable recommendations for both technical and non-technical audiences.
