Designed and implemented a structured ETL pipeline to ingest, clean, and transform a heart disease diagnostic dataset. Implemented data imputation and handled outliers for key variables, including the number of major vessels coloured by fluoroscopy and thalassemia, to enhance data quality and reliability. Conducted exploratory data analysis (EDA) in Python to identify trends across 10+ risk factors, including age, gender, blood pressure, heart rate, chest pain type, cholesterol levels, exercise-induced angina, resting ECG results, blood sugar levels, uncovering correlations and patterns critical to heart disease risk. Built an interactive dashboard in Power BI for easy insights to stakeholders. Documenting all phases in detail has ensured clarity over the process, reproducibility, and scalability while also providing data-driven recommendations to support heart disease prevention strategies.
