About
I am a data-driven analyst skilled in SQL, Python, Tableau, and Excel, with a strong focus on turning complex data into actionable insights. I am seeking opportunities as a Data Analyst or Business Analyst where I can support decision-making and drive measurable business impact.I recently graduated with a Master of Science in Business Analytics from Pepperdine University, where I gained hands-on experience working with real-world datasets and business problems. My work focuses on data analysis, forecasting, and building dashboards to communicate insights effectively. In a recent project analyzing a ghost kitchen company, our team evaluated operational data to understand store performance. I was responsible for data cleaning using SQL and building a predictive approach to compare with regression results. Our analysis identified 21 underperforming stores and supported data-driven recommendations. I enjoy solving practical business problems with data—whether through analysis, visualization, or modeling—and aim to deliver insights that are clear, actionable, and impactful.
