Welcome to my professional portfolio!
I’m a final-year Data Science major at UMGC, with a Data Analytics Certificate from Purdue University and the Google Data Analytics Certificate.
My academic and certification training has given me hands-on experience in SQL, Python, machine learning, and visualization.
This portfolio highlights projects that demonstrate my ability to turn raw data into actionable insights for real-world decision-making.
- Languages: SQL, Python (pandas, scikit-learn, matplotlib, seaborn), R
- Tools: Tableau, Power BI, Excel, SQLite, Kaggle, Jupyter
- Techniques: Regression, Classification, Clustering, ETL Pipelines, Data Visualization, Fairness & Bias Mitigation (AIF360)
- Objective: Built a predictive model to identify individuals at higher risk of stroke.
- Approach: Applied logistic regression with feature preprocessing and model evaluation.
- Impact: Achieved ~78% accuracy and strong recall, showing how predictive analytics can support early health interventions.
- Tools: Python, scikit-learn
- Objective: Explored natural groupings in chemical properties of red and white wines.
- Approach: Performed K-means and hierarchical clustering with PCA for visualization.
- Impact: Identified acidity and alcohol as key drivers of quality, uncovering insights that could inform product development and quality control.
- Tools: Python, scikit-learn, matplotlib
- Objective: Analyzed annual campus crime reports to identify safety trends.
- Approach: Cleaned and aggregated data, then built dashboards and visualizations.
- Impact: Produced actionable insights on incident patterns that could guide policy and safety resource allocation.
- Tools: Python, Tableau
- Objective: Designed a pipeline to consolidate three years of candy order data.
- Approach: Built a SQL-based Extract–Transform–Load (ETL) process with calculated fields.
- Impact: Delivered a unified staging table that streamlined reporting and enabled future sales forecasting.
- Tools: SQLite, SQL
