Tolu Adeleke

I’m a results-driven Data Analyst with a healthcare background, focused on turning messy clinical and business data into clear insights. I bring hands-on experience across data cleaning, EDA, dashboard development, KPI tracking, and data storytelling—so stakeholders can make faster, better decisions. My work also strengthens data-governance habits from clinical settings, including accurate record management and strict confidentiality.

In my healthcare internship, I managed and maintained accurate patient records for 500+ interactions while supporting reporting quality by cross-checking entries and reducing manual errors. I also worked on clinical datasets using data-wrangling techniques to improve consistency and reliability across departments. Through my portfolio, I built interactive Power BI dashboards (including a patient analytics dashboard covering 55,500 records with 5+ DAX KPI metrics and dynamic slicers) and an end-to-end body composition analysis dashboard, where I performed thorough Excel cleaning and created calculated metrics for deeper insights.
