Education

BA in Supply Chain Management
MS in Management Information Systems

As a Data Analyst with over 4 years of experience, I have a passion for uncovering insights and solving data-related challenges. Whether it's resolving data issues, automating workflows, or creating compelling visualizations, I thrive in transforming raw data into actionable business intelligence. I bring expertise in Microsoft Excel, Power BI, Tableau, Tableau Prep, SQL, and Python, tools I use to simplify complex data and drive business decisions. My background in Supply Chain Management (Bachelor’s) and Management Information Systems (Master’s) gives me a unique perspective on data and its critical role in operational efficiency. Beyond my professional life, I believe in continuous learning and balance. I enjoy traveling, playing sports, and, most importantly, spending quality time with my family. My approach to life is simple: "Learn - Play - Repeat.".
