I seek a collaborative analytics role where I can build automated ETL/reporting solutions, create impactful dashboards, and grow technical expertise while driving measurable business outcomes.

I am a detail-oriented data analyst with 2+ years of experience transforming complex datasets into actionable insights that support business decision-making. I build automated reporting workflows, design ETL pipelines, and create interactive dashboards in Power BI and Tableau to improve operational efficiency and executive decision-making.

I have hands-on experience with MySQL, PostgreSQL, MS SQL Server, Python, and advanced Excel, and I collaborate effectively across cross-functional teams to deliver analytics solutions on time. My work has reduced manual processing by 35%, cut churn through predictive modeling, and improved reporting turnaround and data quality across organizations.
