What I'm looking for

I’m looking for a role where I can deliver data-driven insights with SQL/Python and Tableau/Power BI, build reliable ETL/data pipelines, and partner with cross-functional teams to improve operational efficiency and decision-making.

I’m a data professional who turns complex data into actionable decisions through SQL, Python, and Azure, backed by hands-on work building dashboards and data pipelines. At Crowddoing, I used segmentation, statistical modeling, and exploratory analysis to improve bed occupancy resource allocation by 15% and reduce reporting time by 25%.

My work also emphasizes data integrity and reliable delivery: I authored advanced MySQL scripts, engineered data pipelines with window functions and optimized CTEs, and resolved duplicate or inconsistent member records to strengthen reporting accuracy. I’ve led experiment-driven optimization through A/B testing (20% user engagement lift) and built unified KPI reporting frameworks in Tableau for executives, while earlier roles included ETL development for large-scale Oracle-to-SAP migrations.
