Featured Project

Stroke Risk Analytics Dashboard
Interactive Power BI dashboard built on a healthcare dataset of 5,110 patients to analyze stroke risk indicators through KPI tracking, demographic filtering and risk-focused visual analysis.
What I built
I designed a dashboard with KPI cards, age analysis, BMI category views, smoking-status breakdowns and health-risk comparisons to make patient-level insights easier to understand.
Why it matters
The dashboard helps highlight how stroke prevalence relates to age, hypertension, heart disease, BMI and glucose patterns, turning healthcare data into a more actionable reporting view.
