Data Analyst with hands-on business ownership experience. Applied SQL, Python, and BI tools to real P&L decisions across hospitality, healthcare, finance, and HR — delivering ML pipelines, automated models, and KPI insights that drive operational impact.
I'm a data analyst who bridges the gap between raw data and real decisions. My work lives at the intersection of rigorous statistical analysis and clear, compelling storytelling — because insights that can't be communicated don't drive change.
With an MBA in Finance & HR, and hands-on business ownership in hospitality, I've built ML pipelines in Databricks, automated Excel/VBA models, and KPI dashboards that directly informed P&L decisions across healthcare, finance, and operations.
I believe the best analysis asks a better question, not just finds a better answer. I thrive where ambiguity is the norm and clarity is the goal.
Each project starts with a real business problem and ends with a measurable outcome.
Designed a fully automated Excel/VBA model for multi-scenario cost and savings analysis, eliminating manual recalculation and improving evaluation efficiency. Modeled 3+ intervention scenarios to identify the highest-value cost-reduction strategies for decision-makers.
Built scalable PySpark ML pipelines in Databricks to process large clinical datasets, evaluate classification model performance, and surface statistically significant gender-based bias patterns with corrective recommendations.
Built and compared 3 ML models (Random Forest, KNN, Linear Regression) with feature engineering across multi-variable financial datasets to optimize forecast accuracy. Random Forest outperformed baseline assumptions after cross-validation, identifying key performance drivers across asset classes.
Built KNIME workflows and Tableau dashboards to analyze AI-assisted diagnostic tool impact on radiologist speed and accuracy across large-scale radiographic datasets.
Transformed unstructured student sentiment data into quantifiable behavioral indicators using R and NLP; regression analysis demonstrated a significant EI-to-performance correlation.
