What I'm looking for

I seek data science roles using analytics, modeling, and visualization to improve decisions, with collaborative teams, clear impact, and opportunities to scale models and productionize pipelines.

I am a data scientist focused on environmental health and operational analytics, combining strong statistical foundations with applied experience in Python, R, SQL, and BI tools to deliver data-to-decision solutions. I have built ETL pipelines, validated predictive models, and developed interactive dashboards that improved model performance and operational reporting.

My work spans disaster mobility analysis, healthcare operational analytics, and financial reporting automation, with achievements including a ~15% ROC-AUC improvement from feature engineering, automated KPI dashboards that reduced manual reporting by ~25%, and a 40-page master’s thesis on evacuation and resource-flow optimization.
